From what I've been told it's more of a peace of mind thing. I ran stock plugs for a while and my car ate those... Colder plugs with a tune are kinda a must from my experience.
I installed my new plugs on friday. All i have to say is wow what a difference. the car idles a lot smoother. here the stock plugs, i am glad i changed them and did the check valve mod in the pvc system. much oil very bad.
every engine is different and mine might be a little worse due to the az high temps this summer but it is a highly recommended mod and thanks Adam for making the swap super easy by pre gapping them.
Yeah definitely. Adam's plugs came in today and I've had my upr dual valve catch can for a few weeks and just been too lazy to put it in and do the pvc gut:shrug:
Yeah, Adam had me switch out my plugs and it was one of my best upgrades so far! haha. Can't really beat that $40 price tag either. I hate gapping plugs!
My stock plugs looked the same as the ones above in the picture. Replaced them with Adams pre gapped plugs and the car runs great. For $40 why not? Lol don't even have to gap them.
