What spark plug

#1 Post by OCR »

I am fouling the stock plug (cr10ek?), what plug is everyone running... the 9 or the 8?

I run the 9 seems to work fine for me.

I also run the 9.
But if you are fouling plugs, I'd drop the offset a little and lean it out.

did you use the D&M kit to "lean it out" and what is involved in doing this? just notching the offset down a little?
