just out of curiousity, what plugs are you guys running and at what gap? right now im running NGK, can't remember the heat range but they are colder than stock and are gapped at .028. i just want to make sure that what i am running right now is optimal for my setup, which is a mild y7...just a ported, polished and milled head and a delta cam, skunk2 intake mani, decent bottom end at 9.8:1 compression and 10 psi. thanks in advance for any feedback.

 

this is a topic that I have heard alot of different opinions. I have mine ngk a step colder and gapped between 33 35. I had them gapped at like 25 but the speed shop told me to gap them more because i wasn't even burning fuel with such a small gap.

 

For every 75-100hp added go 1 step colder.

For every 50hp added tighten gap by 0.004.

For example, if a d16y8 is now pushing 220hp.....you would go 1 step colder (level 5 to level 6) and decrease gap by 0.008 (so from .044 to .038) approximately.
