I'm changing my oil tomorrow and also decided I was gonna put some new spark plugs in. I know these questions have probably been covered numerous times but I'm on my phone and the search sucks. I'm going with the ac delco plugs because that seems to be what most are using. Iirc they are supposed to be gapped at .032? I am completely stock atm but in the spring I have a k&n intake, zzp intercooler kit, zzp 3in catted dp that I will be putting on and getting tuned for. Will I have to change anything with the plugs when I get all this done. Should I be going a step colder or anything like that? I don't want to do it twice if I don't have to. Thanks guys

Also what are the plugs supposed to be torqued to? 15lbs? Its an 08 ss btw

 

Stock plugs at stock gap

 

plugs = snug

 

So regardless of what setup I have I should stick with the stock plugs and gap(.032?)

 

i still have stock plugs in mine and it runs dandy

 

Mine are gapped at .35 no problems

 

Alright sounds good. So gapped anywhere from .032-.035 is fine? And no one has an exact number for how much the plugs should be torqued besides snug?

 

Out of the hundreds of plugs I've change I've always just made then hand tight then some and never have had a problem. Just don't tighten them to much, you might strip the threads then have a big problem.

 

Ok thanks alot

 

There is no toque spec for plugs. It's just 1/8 turn past tight. My stock plugs came at .35, and I left them there. I have a 21 psi tune and HPT. I have logged no misfires.

 

thanks a lot. everything went well. plugs were pregapped to .035 had to adjust one a little. when i tune it im probably not gonna go over 22psi

 

 

I'm running stock plugs at stock gap. runs fine. Remember that you're putting plugs into an aluminum head. A small dab of high temp anti seize goes a long way.

 

thats the way ive always done it. go to snug and got a 1/8=1/4 turn fast snug and call it good

 

Didn't use any anti seize...
