Spark Plugs for TT
Hey guys so I bought the NGK Iridium IX (1-step colder) spark plugs and wanted to know what I should gap them at. I'm running the Greddy TT 18G on the DE motor, thanks!

Gap should be good as shipped from NGK.

I don't even gap them, never had an issue with blow out, I run 9lbs though.

I never gapped mine and I'd hit 28 psi with no blowout

^how much dwell will you run? I know the haltechs are set at 4.5. You ever run more than that at high rpms?

Just be extra careful gapping iridium plugs.

No problem. You won't need to gap them if anything just check to make sure the gap didn't change due to shipping and handling.

the lfr6a (ngk 6668) is a better choice as they are already gapped at a turbo appropriate 0.035"
