NGK TR6 Spark Plugs

I installed a set of NGK TR6 spark plugs on a supercharged LS1 Corvette engine. Due to the extra compression pressure from the supercharger boost, I needed a cooler spark plug with less clearance. Now it runs much quieter than with standard platinum candles. I have used these spark plugs in other high performance Chevy small block engines and have always been pleased with the results.

Pros
  • Pleasant
Cons
  • Legacy Model
