What spark plugs are you using with your F/I? My car hasn't been starting very easily lately and I think my plugs are fouled (I was running WAY too rich for a while). I'm looking to replace them, so give me some brand info and where you picked them up please.

Thanks,

Kevin - Use NGK (2) steps colder.

NGK 1-Step colder plugs; they were installed by Stillen when the SC was put on.

Part Number: NGK7654

Stillen Stage 2 Supercharger
Stillen CF Hood
NGK 1-Step Colder Plugs
Z-Tube

 

Seems like that is a Stillen part number. I searched the web and found that PLFR6A-11 is the manufactuers part number. I ordered 6 of them and hopefully my little problem will go away.

Thanks,

I am also using the NGK, one step colder. Have 14,000 miles on the ATI now and still going smooth and strong. So far.
