so I'm going to buy some new spark plugs pretty soon. I was looking at some densos and cars they have one-step plugs and two-step plugs? what does that even mean? also, should I go with Denso or hks? I believe at the moment I have some hks plugs in my car.
 
denso - cheap and last less time. like 10-12k miles.

hks - cost more but last longer.

a colder plug brings the electrode closer to the plug base so its not as affected by heat which can lead to eating the electrode away or pre-detonation

you can slap 2 step in and itll be just fine. if you only plan to do mild modding, one step is ample. its not make or brake in this situation which one unless going all out in performance than 2 step for sure
 
Please get HKS, after 2 broken/blown densos, it's worth the extra $. Although I can change plugs like a champ now. ;)

yeah naw lol. I'm buying hks again. I just wasn't sure about the one and two-step think. I currently got like 30k miles on my hks. I need to replace them asap

did they break as you were driving or what happen?
 
Had one blown when I went WOT on a highway merge ;) Basically shut my car down, threw plug code. Limp mode, turbos don't spool so you are on just normal engine power. I threw my stock nkg back in so i could drive. Cleared code via battery restart. Pulled plug had its ceramic cracked. #3 plug.

2 months later just about the same thing, but this time no code, but if I stomped it, car would buck and throw a fit and eventually limp mode, restart would make everything normal again but turbo's wouldn't spool anymore. Pulled #6 plug thats under the ITM (Sucks), then found ceramic had actually separated into plug shaft. So had to pull the ITM off completely.

Put 1 more Denso in just cause they are so much cheaper. Still never could WOT properly. Found that my used JB4 still had old none defaulted settings stored in it. Cleared that. Things got better, but still wasn't 100%.

Swapped to HKS, WOT all day long with/without the JB4. SMH, should have just bought the HKS's first. All this could also be 100% my fault for over tightening as I only initially installed without a torque wrench, but I don't feel I did that. (Also don't buy the wrong ones for the 3.3, got my new set for Christmas from my brother but he got me the 2.0's first. :) )

If doing it yourself, please report back. I'm tempted to get the couple things I supposedly need at Harbor Freight to do this myself (swivel adapter and socket extension), but I'm worried youtube makes it look easier than it actually is.

I've done plug changes before, just not recently since none of my recent vehicles hit the required swap interval and definitely not on an engine where they're as buried as a few seem to be on the Stinger [all this assumes you're running the 3.3TT].

yeah my fear at the moment is a blown spark plug xc. this weekend I'm going to pull all the easy ones out to check them out.

it's honestly super easy. if it's your first time it will probably take you an hour. they're all easy to take out besides the middle passenger side plug. you will need to separate the coil pack to remove it just be careful nothing falls out of the coil pack because you will have a different annoying ass problem waiting for a new piece.

again very easy! make sure you got the right parts and make sure you have a spark plug socket with thin walls. that helped me out but I forgot why exactly.
