NGK TR55 spark plugs for 97-13
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,
Iridium IX - The ultimate evolution of a performance spark
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.
