ok so last night i was moving my truck out of the pasture and i noticed it missing alil bit but it wasnt a big worry to me at the time so i just drove it up to the garage and parked it. today i pulled the plugs t find out with one was bad and i found it, and a few others that i think have run out of life. but heres the thing, right now the plugs i have in it are bosch platinum +4 plugs. but since i decided im just going to change all 8 plugs before this season im curious about what kind of plugs you guys use in your rigs. or if there a good performance one or something cause they will be going into a dirt track race motor. and im wondeing is there any suggestions for what i should run? thanks.

Everyone I know that builds motors still use the good old AC delcos but change heat range depending on the motors set up.

Yeap, I run AC delco, they make spark, all its gotta do. lol

ac r43ts is probably recomended. i run 44t, slightly shorter electrode because i have tall pistons
