Colder spark plugs

Post by M3fan4eva »

Do I need colder spark plugs for my S1 kit in my E30M30? If so, where could I find them?

colder plugs are not necessary for s1......they can't hurt though. when i was running my s1 kit, we changed the plugs to 1 step colder and messed with the fuel and picked up 35 rwhp in between runs. when i was up to s3, i ran stock heat range plugs with a close gap up to 15 psi (only since we had nothing else on the day of the dyno). i have since switched to ngk bkr8e ix plugs and they work great. no detonation issues tested to atleast 21 psi on pump gas.
