Brisk Spark Plugs

[Vladec]

Huh.
Multi-tip designs: E3 has been doing this for a while. They were the darlings when they came out and now generally regarded as snake oil.

Gap: We know the ignition power on the stock coil/ECU is marginal because the gap needs to be closed when running higher boost. Running a wider gap only makes that problem worse. Now this plug PLUS Tork's ignition modifications MIGHT put more spark in the chamber.

Indexing: For those looking for an extra 0.1% of engine power, indexing a traditional plug so the electrode is away from the exhaust valve can give very slight improvements at the edges of the engine's performance. This is a very old drag racing trick. But for anything other than the very ragged edges of racing this is completely pointless.

Remember that spark plugs will only take as much energy as they need to jump the gap. Some ignition tricks are useful on carbureted engines where the A/F mix can be wildly rich or lean at times. And, of course, nitro engines where they're trying to make a quart of nitro explode inside a cylinder slightly larger than a quart.

The silver tip, if it really is silver, seems like an extrememely bad idea for a street car. That cannot last very long.

Snake oil. Cool looking, and definitely a unique center electrode design, but still snake oil.

I emailed them with everyone's questions / concerns. Lets see what they come back with.

Not just E3, but also Bosch and NGK have used that design. Take a look...




I completely agree with the silver electrode - I cannot see that thing lasting for more than a few thousand miles before it wears down too much. Also, despite silver being excellent at conducting energy, there is still that gap it has to jump, and we don't know how big it is on those plugs, plus adding boost only increases the resistance the spark will see, making it even harder to jump that gap.

Indexing plugs CAN make more than a 0.1% increase in HP - though it depends almost entirely on combustion chamber design. They used this a lot in older cars because spark plugs A) were not perfectly centered at the top center of the cc, and/or B) the plugs came in at an angle relative to the piston. Indexing your plugs would allow the spark to 'see' more of the air/fuel mixture (by moving that ground electrode out of the way) thus creating a more effective burn. That being said, such benefits do not apply to modern engines, as the plug is perfectly centered in the cc, and aimed exactly downwards, so in this case the most performance increase you'd see would be about 0.1% I suppose, haha.

One thing that the Brisk plugs do have going for them is the projected tip. The OEM NGK's have this feature as well, though.

Personally, I'm still one of the few who thinks that - so far - the OEM plugs are the best.

Ok guys so this the response I got below from Brisk. Enjoy as it's a pretty long read



We appreciate you reaching out in regard of our products and getting some valuable answers directly from the source. As we all know in the forum community information can be a bit misleading at times and may not be "complete", there are a lot of variables to account for when making spark plug selections just like any other component for your engines.



Unfortunately, the standard LGS variants like the EOR14LGS design have a very large gap that is not adjustable and for applications that see cylinder pressures such as the stinger platforms it is not a great fit. The LGS plug is rather flexible but the effective gap of the plug ranges from 0.035" - 0.060".. any application requiring a gap lower than 0.035" generally we do not recommend the standard LGS design for.



For naturally aspirated use the standard LGS is a fantastic spark plug and carries an average lifespan of around 45,000 miles for naturally aspirated use and we do offer a variation of the LGS design with a tighter gap specification which is our LGS-T which carries an average lifespan of around 60,000 miles but unfortunately in the thread construction your cylinder head requires we do not offer the LGS-T variant.



What we sell primarily for these applications and applications that have relatively high boost pressures from factory is our Silver Racing design. This is our premier forced induction application spark plug solution, they do utilize a silver center electrode as well and carry an average lifespan in a factory forced induction application of around 20,000 - 25,000 miles. For modified applications the lifespan is subject to be shortened but we still see moderately modified applications seeing 15,000+ out of a set.



The most popular plugs I've seen on the web for the Stinger platforms are the NGK and HKS plugs, some of the HKS/NGK racing series plugs that cost $25-$40+ a piece our silver racing is a direct replacement for and have become very high in demand for the european applications such as BMW, Audi and VW turbo engines due to their improvement in performance by allowing for better tuning flexibility and price point ($10.99/each)



Here are some cross references I've gathered for your community, should you have any further questions or concerns, please feel free to shoot me an email or give me a call and I'd be more than happy to help with product selection!

We also offer an additional heat range colder than no other manufacturer does for this platform:



Brisk ER08S Silver Racing Non-Projected Insulator Tip

After looking at the forum you mentioned there seems to be some misunderstanding by some of the members as well in regard of our Silver Racing plugs - one member stated in regard of the ER12YS plug -



" They say it has a projected tip, which is a nice feature that the OEM NGK's utilise (though it doesn't look like it's a projected tip); but, the rest of the plug looks like garbage. That center electrode and the ground electrode look really bad. It isn't an iridium plug, so it wouldn't last very long at all, and it might take more energy to create a spark. Also, with that HUGE ground electrode you will have tons of shadowing. All 3 popular plugs for our cars already have a factory trimmed ground electrode.

But hey, if you want to try them out go for it - just let us know how it goes."



So let me shed some light - First, the ER12YS plug is a projected insulator tip and that image is very poor it is soon to be replaced with a proper image which will represent the product much better.



Projected insulator tips are primarily beneficial for combating carbon deposit build up on applications that see extended periods of idle time or low duty cycle driving such as stop and go traffic. Aside from that there really is no benefit for performance and racing applications, we recommend non-projected insulator tips for modified turbo applications primarily as you can be more aggressive with the timing curve and often make more power due to the plugs ability to dissipate heat more effectively which combats knock and pre-ignition. It also makes the plug more durable for increased longevity as the ceramic insulator nose isn't subjected to the harsh turbulent environment that a projected insulator tip spark plug is.



All of our plugs come with cut back ground strap electrodes, they are trimmed back for increased spark exposure, our ground straps are wider and beefier which is beneficial for heat dissipation and decreases the chances of the gap opening or closing due to excess heat retention (common issue on turbo cars)



Silver is the best conductor of thermal heat and electricity out of any other metal alloy used in spark plugs. Copper being number 2 and gold being number 3, Iridium doesn't even make the top 25 on the list in reference to electrical conductivity. This reduces voltage requirements and enables the plug to utilize a larger diameter center electrode while maintaining low ignition requirements which also increases the heat dissipation capability as well which gives silver a wider heat range.



Using a silver center electrode actually reduces the required spark energy required to jump a specified gap, our plugs require less energy to fire than the iridium spark plugs, iridium is also a very poor material for performance and racing use as it is a very poor conductor of heat and electricity, this is why you see extremely small diameter iridium tips, any larger in diameter and they would not be able to fire the gap effectively. Iridium plugs often lead to pinging and pre-ignition in modified turbo applications due to their poor heat dissipation properties. Our Silver Racing design will allow you to tune more aggressively before seeing spark induced knock than an iridium plug of equivalent heat range.



The quality of our products and materials used is industry leading, we have been producing spark plugs since 1935, all of our components are manufactured in house on our state of the art assembly and production line from the shells to insulators, etc.., We specialize in performance and racing applications and are the premier forced induction and nitrous plug on the market!



Please feel free to share this with the forum as the more information we can get out there in these communities the better understanding these communities will have in regard of spark plug characteristics and understanding of the function of spark plugs.

Furthermore - "Huh. Multi-tip designs: E3 has been doing this for a while. They were the darlings when they came out and now generally regarded as snake oil."



E3 plug functions completely different from our LGS design. Our LGS design is a semi-surfcace discharge spark plug, not even comparable. E3 started manufacturing spark plugs about 7 years ago and outsources all components.



Our LGS design is patented and has been on the market for well over 2 decades now, there isn't even remotely a comparison.


The end.

Guy definitely knows his product... thoughts? Pretty interesting as he doesn't recommend the multispark plug we identified

Wow! Hot damn, he even called me out!! Haha. So it looks like I was on the right path with the equivalent plug to the Denso's that we see so often here. Perhaps I could get a set of ER14YS plugs and see how they compare to OEM. I'd like to trim the sides down from the ground electrode end.

I get what he's saying about Iridium vs Silver; but the reason why iridium is so popular is because it's such a hard metal, and extreme resistant to corrosion and wear from the combustion process. Even though their plugs have that huge ass ground electrode, I think that there will still be more of a gap created by the silver center electrode wearing down... BUT - the added benefit of removing heat with the larger ground and center electrodes stand to benefit things, but how much is unknown in our case. To me it seems akin to just running a colder plug, as it's all about heat transfer anyway.

As for the projected tip, I base my info on an old article from EnDyn back when I was working on Honda's. He, Larry, talked about ignition giving the best burn when centered right in the middle of the air/fuel mixture, as in, centered in all 3 dimensions. So if you imagine the compressed air/fuel mixture as a single piece of coal, it would burn the fastest if you lit it from within right in the core. That said, a projected tip generally has the same concept - ignition right smack dab in the middle of the fully compressed air/fuel mixture, so you have more of a 'center out' type of burn instead of a 'top down' burn.

There most certainly is a possibility that I am not understanding what Larry said, and my own interpretation is totally wrong. Even so, I still think the projected tip is worth it if it only reduces carbon buildup within the CC. If that's the benefit you get at the cost of ever so slightly shorter lifespan on the plugs, I'd say it's worth it, as most of us daily drive our cars and carbon buildup will ultimately increase chances of seeing detonation. Who knows, maybe it even contributes to the dreaded, but inevitable, intake valve gunk.

If I buy a set I'd go with the projected tip. But, that's just me.

Now I want to try these things on the Dyno, back to back, and see if what he claims actually makes any difference. Personally, I doubt it does, but it does make me curious..

 

[Toddasaurus]

This is why you ask the vendor before you take advice from a forum.

There are two sides to that. The vender will pretty much always give a biased answer. It's best to get all the info you can from a variety of sources.

 

[turboAWD]

I wonder if Terry has any opinion on these.. if they really want to sell a bunch, they should ship a set to Terry for free so he can dyno / 1/4 mile test it. If he can show better ignition / burn / power, these things would sell like hotcakes. I mean - we all know spark plugs are a weak point for our cars. I wouldn't really care much about this on another car, but on *THIS* car, I'm interested.

I'll chip in $5-10 if Terry agrees to test a set.. Anyone else?

 

[Ticketmaster]

With the silver racing series being recommended for our car when we can only expect 15,000 to 25,000 miles out of them...that's a tough sell for someone that daily drives their car like me. Unless these plugs are consistently making at least 5 more whp or were the only plugs I had zero issues with I'd have a hard time justifying that service interval. I would be very interested in the LGS-T if they decided to make it for the stinger! In any event it's exciting to see another option as well as hearing from those who are running them.

 

[StungBlueGT2]

Gotcha. I read all that after I posted my question, haha.

I noticed a couple things. 1 - I can't help but wonder how long the silver electrode will last, as it's much softer than iridium, and subsequently will probably wear down much quicker. 2 - Brisk recommends their other plugs for FI engines. But if guys are having success with these in our engines, then it probably doesn't matter.

All that being said, these still look fancy and I REALLY like the concept!

The silver electrode is softer but it’s recessed and much larger than Densos or other iridium tip plugs. I was told they are expected to last 20k-30k which is similar or higher than most high performance plugs.

My one friend with about 450whp+ & 20psi+ has over 15k on them with no issues or wear showing. He any many others used Densos or HKSs and only got about 8k-10k before needing replacement so that says a lot about them imo.

Also I don’t see in that article where they recommend their other plugs for FI engines. Can you please clarify so I can see it too?

Here you go....






There is no mention of forced induction on the other, open tip design plugs. Take a look....






Hence, inferring that they're not recommended for FI. Also, the guy himself said, "Unfortunately, the standard LGS variants like the EOR14LGS design have a very large gap that is not adjustable and for applications that see cylinder pressures such as the stinger platforms it is not a great fit."

If you think about it, the only real "feature" that these plugs have that the others don't are the silver center electrode. That's pretty much about it. They say their ground electrode is thicker and more heavy duty, but it's hard to tell by the pictures alone; and they're discounting the fact that the OEM NGK and the HKS plugs have the Platinum chip on the ground electrode which helps keep the gap consistent and reduces wear on the ground electrode.

Thanks for sharing and clarifying that you were just inferring they weren’t recommended for FI engines. It actually doesn’t say that anywhere, but I see how you made that assumption.

Few things to keep in mind and reasons why the LGS plugs are working well in our Stingers. I’m not disagreeing with Brisks comments but the parameters and benefits of the LGS plugs do actually fit our engines.

First, the Silver Racing plugs are made for high output racing engines with hard to ignite fuels(alcohol, nitromethane etc). Almost all of them are extremely high boost forced induction and/or Nitrous engines. Our engines only run about 12psi(stock) to 20psi(tuned) and don’t really fall into those categories, at least not yet. Also all of the 4 recommended applications listed for that plug don’t apply to our Stingers.

Second, the beneficial plug feature you cited for forced induction engines actually refers to the silver electrode and it’s advantages as a superior thermal & electrical conductor. The LGS plugs share the silver central electrode and will have all those same benefits for our boosted engines.

Third, the LGS plugs don’t mention forced induction because as Brisk said they aren’t designed for tight gaps which most boosted engines need for easier spark to break through the air gap. However, since the LGS plugs use a hotter semi-surface spark discharge it takes less energy for the spark to glide along the surface of the insulator than to break through the air gap.

Also our OEM plugs are actually gapped around 0.032-0.036 so they fall into the proper gap the LGS plugs work well with. So between the more efficient and easier spark these plugs actually run very well in our engines.

Lastly, the multiple other benefits that the LGS plugs have do provide better fuel utilization and in tern more power in each compression. This definitely does increase throttle response & power which is very noticeable when switching to the plugs compared to Densos or the NGKs. I’ve driven both Stingers with these plugs before and after install and there’s no doubt they made a big difference in performance. I didn’t believe it at first myself either but after seeing & feeling the proof I can’t deny these are superior plugs in every way.

Hmm. Good to hear. How much are these for a set?

 

[StungBlueGT2]

Hmm. Good to hear. How much are these for a set?

About $70 a set and Carid is the place my friends got theirs.

Just remember they aren’t made for our Stingers yet so they don’t have our model listed. My friends said to just put in a Porsche Macan for the vehicle so it allows you to purchase them.

Lol that's what I read too. I was pretty dismissive of this brand simply because I had never heard of them before (NGK ALWAYS FOR EVERYTHING ((except Ford)). After reading the response from the company tho, I'm actually pretty interested. 15k to 20k miles isn't that big of a deal to me. My WRX had to change the plugs every 12k to 18k so nothing new.

Very interesting shit here. I think I'll have to try these.

I already explained above but if you read Brisks response they “generally don’t recommend” the standard LGS plugs for us due to their large gaps. However, their website clarifies that the LGS’s “generally work well in the applications where the recommended spark plug gap for given application is more than 0.032". Our OEM plugs from Kia are gapped between 0.032-0.036 so they actually fit that description perfectly.

Also the reason tuners suggest tighter gaps while using extra boost is to prevent misfires. But because of the patented semi-surface discharge and silver center electrode they take less energy and are more efficient at producing a spark so misfires don’t happen even under 20psi+ boost.

The LGS-T plugs with tighter gaps may work better for even higher boost conditions and know my friend is already in discussions with the owners of Brisk about developing them for our Stingers.

However at this point a couple Stingers already have and are testing the LGS plugs with great results even after 15k miles and 20psi+ daily driving.

 

[Moses]

There just not vehicle specific. I don't think any manufacturer how stinger specific plugs?...at last not yet?

The problem isn't that they aren't vehicle specific, the manufacturer listed different models that they offer that will work for our vehicles. The issue the manufacturer has with the plugs that are the topic of discussion, is that the gap is a bad choice for turbo vehicles.

What tune/piggyback are these guys running? jb4? Have they sent any logs to Terry? I have some Densos that will go in first, then maybe look at something like this..
