Spark Plugs for TT SRT...

[Mr. Hollywood]

Just curious in what other TT cars are running. My last car was running NGK Iridiums....with JM heads. My current car still has stock heads and I'm running an Autolite 3922. Anything better for my application?

Without a doubt. The autolites suckass. Get a set of Champion RC10ECCs. Daniel Lesser might have a set. The are 2 steps colder and run great cold. The Champions are a standard reach cold plug, you'll love them. PM sent

I run NGK R5671A-8 4554 3 heat ranges colder

non projected tip, standard plug, cheap, change out often. Iridium never sounded worth it to me.

Call your tuner he should be able to offer suggestions based on the setup he built for you.

Copper is the best for turbo cars. Don't mess around with exotic metals, copper will outperform them all.

Is that what Heffner told you to run?
