What Are The Best Plugs To Run And Gap

 

[Bryan C.]

I run the stock AC Delco plugs gapped at .032". They work well for me.

Not sure on your mods but it would probably be safe to recommend AC Delco CR43TS gapped at a tight .035. This will be your best bet.

When you start moving really fast you can look into a bit cooler CR42TS. Also I like the NGK UR5 plug. Gap may get a bit tighter when you start running higher boost levels, etc.

i run the NGK UR5's gapped at .035 like 6sense said. They work great for me.

I run AC Delco CR43TS gapped at .035 - work great for me.

They are a bitch to change though !!!
