Recommended spark plugs?
I need a new set of spark plugs... The Autolites I'm running right now have been fouled out from running pig rich due to poor AFPR adjustments, then lean due to MAF sensor problems.
What plugs would you guys recommend with my current mods? I'd like to stick to Autolites unless anyone knows of a better plug. I need a copper or something with a big electrode, since the car loses a tune very quickly, and I know how easy those platinums are to ruin.
Also, do you guys recommend any particular gap? I've just been using the factory gap.
Thanks.
