3.3TT K&N Typhoon Cold Air Intake System versus K&N air filter replacement

[Dochidalgo]

Please correct me if I'm wrong....
I have understood that more HPs, less MPG (illogical to think otherwise), and the ECUs will do all the adjustments necessary in order to mantain the air/fuel ratio 14 and fraccion parts of air to one part of fuel, invariably.
So, more air entering to the combustion chamber, more fuel will be injected....the cold air is more dense so will push harder to the piston and hence more engine power.
We do not purchase this kind of car thinking in MPG alone, it matters but it's not the main reason to buy this car.
In my particular case, Mexico, the fuel has reached an exorbitant price. So, it seems that the K&N CAI decreses the MPG over the K&N air filter replacements.

I would appreciate the comments of those who have installed one or the other air filter system and the MPG

The K&N Typhoon is a CAI in name only. In reality it is a HAI.

From what I've read in the past a HAI will actually help with fuel economy.

From: Warm air intake - Wikipedia

All warm air intakes operate on the principle of decreasing the amount of oxygen available for combustion with fuel. Warm air from inside the engine bay is used opposed to air taken from the generally more restrictive stock intake. Warmer air is less dense, and thus contains less oxygen to burn fuel in. The car's ECU compensates by opening the throttle wider to admit more air. This, in turn, decreases the resistance the engine must overcome to suck air in. The net effect is for the engine to intake the same amount of oxygen (and thus burn the same amount of fuel, producing the same power) but with less pumping losses, allowing for a gain in fuel economy, at the expense of top-end power.

I have the K&N drop in filters installed. I did not notice a difference in power and I don't really pay attention to the fuel efficiency. I will say that the drop in filters keep the intake isolated from the hot air of the engine bay. The Typhoon system exposes the intake to the hot air but you get the "ppsh" sound that many people enjoy.

For both the Typhoon and the drop ins K&N claims a horsepower increase. I don't believe that for one second. Actually I'm skeptical of any company's claim of horsepower increase. If the results aren't provided by a non-biased third party they should be taken with a grain of salt, in my opinion.

little confused here how do drop ins keep the intake isolated from hot air ???? they are drop in and in the factory air box just like a factory fit air filter would be correct me if I am wrong .... furthermore they K/N drop ins just allow for more air flow again correct me if I'm wrong. Or are you just saying using drop ins keep it isolated because they utilize the factory air box compared to the HAI? I'm not busting balls I seriously got confused reading that lol

The K&N Typhoon deletes the factory boxes and places the filters directly in the engine bay exposing them to hot air.

The drop ins are sealed off from the engine bay by the air box to keep the surrounding hot air out (as much as possible).

I’m considering the K&N Drop In Filters. Have those, like Kamauxx, been happy with their choice? Other than being washable and reusable do you notice anything at all? If I do it now I’m just throwing away two perfectly fine filters. Should I just wait till it’s time to change them? So many questions...
Thanks for any advice.

I did my drop ins about 3 months ago. I noticed quicker acceleration right off. I mean it's not blazing speed, but it did appear to "breathe" better. Basically I'd say if you can afford the $100, I'd do it. I could have waited until mine needed to be changed, but I'm impatient.

I know, do it now or go home. Wait I am home. I’ll do it now or at least when I get an appropriate coupon!

I wouldn't buy them if you're looking for a performance increase. I didn't notice any change.

I've actually just purchased new intakes so the drop ins will be getting stored soon.

What you go with?

JTs CAI.

Burst my bubble why don’t ya. I was wondering if I’d notice anything or I’d have a placebo reaction. I just spent a hundred dollars it must be faster! I think I’ll cool down. I’m not going the CAI way.

Well post updates and pictures.

I found a good deal with the direct replacements K&N air filters. I could not wait to install them, and just like Scott described, I noticed quicker acceleration checked with my trusted dyno butt and a better exhaust sound, even in the eco & confort mide. Placebo effect??, maybe, but I am happy.

On long hwy drives, I’ve experienced better mpg in just about every car I’ve put the drop ins in. I noticed a little better throttle response w/ the drop ins on the stinger but I would say it’s nothing more than a marginal performance increase. For me the drop ins have always been for better mpgs on long drives. Just waiting for a suitable design for an enclosed cai. I may modify the the stock box where it meets the panel connecting to the grill. The design seems to be a bit restrictive- probably why JT designed that portion of their intakes the way they did.

The K&N Typhoon CAI comes with a "heat shield" box for the air intake filters. It's not totally sealed off from the engine bay but offers some protection as a heat barrier. Personally, I love how the car performed before the mod and even more so after.

Could always go old school and modify the stock air box by cutting more holes in it, then dropping the K&N panel filters in.

I used to do it all the time years ago. That being said, i haven't done it a more expensive car.

All that would do is open the box to the hot air from the engine bay.

worth a shot

worth a shot

With what goal in mind?

my idea was worth a shot, as in.....oh well, it was worth a shot, but wouldnt work.
