NGK TR6 Spark Plugs, One heat range colder than stock, gapped at .035 (Works well in Nitrous, Supercharger, or High-compression motors)
Set of 8 Spark Plugs, Recommended for C6 Z06 LS7 Engines by NGK
C6 Performance recommends NGK brand spark plugs for all of their high performance engines. NGK performance copper spark plugs are available in a variety of heat ranges for your specific application. 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."
V-Groove Explanation Quenching Effect
"The amount of spark which is absorbed by the center and ground electrode is referred to as the quenching effect. The V-Power plug is designed to draw spark to the edge of the electrode. Thus, the quenching effect is minimized, resulting in more effective, complete combustion."
Iridium IX - The ultimate evolution of a performance spark plug.
It may be time to invest in precious metal futures. NGK Iridium Spark Plugs represent the ultimate evolution of spark plug technology and performance. Iridium allows for a center electrode 75 percent the size of a platinum electrode and 24 percent the size of a conventional nickel electrode.
The fine electrode tip is engineered for greater ignitability. And it's in the design of the iridium tip that makes Iridium IX a better spark plug. The electrode is not too thin and not too thick. It's just the right size to reduce the voltage required for spark and to maximize the overall longer life qualities of iridium.
