Corvette Central recommends NGK spark plugs for street and performance applications. These plugs typically result in quicker throttle response and an overall smoother running engine.
Ignitability of V-Power Spark Plugs
"NGK's unique V-Power design directs the spark to the edge of the electrode where it can develop more rapidly. This allows easier and more complete combustion of the air/fuel mixture. The increased ignitability allows the engine to burn air/fuel ratios that would otherwise be too lean."
