Spark Plug Recommendation......

Any help is greatly appreciated......

See you all at INDY!!!!!!

Hi Wade,

I don't know about others, but I've been an AC Delco Rapid Fire fan for most of this decade, and I won't forget that my used set of them outperformed a new set of Bosch Platinum + 4 plugs I tried around 2002. I'm not sure about heat ranges though, because I've just been using the OEM recommended part number for my application (which I know is no help to your set-up). I'm also curious about those E3 Diamond Fire plugs, but if I find out that their foreign made, they won't go in my car...good luck at Indy!

I'm amazed that you haven't gotten any replies to your post prior to mine, but I think most of them are on the racing side of the Stock/Super Stock forum....

I like NGK's in my 10.5-1 505, I change plugs once a year.

NGK's race plugs work good and cost $2.50-$3.00 a piece.

I run the Autolite race plugs...it's what Bruce gave me.
