NGK V-Power Performance Spark Plugs

3951 NGK V-Power TR55 Spark Plug - PRICE IS EACH

Replace your stock plugs with these NGK TR-55 Plugs, there are one half step colder than stock. These are a must when changing out to a supercharger, turbo, or nitrous. The colder plug will help prevent detonation from the increased heat the motor see's from higher boost levels.

V-Power spark plugs are a patented design by NGK to improve ignitability and reduce detonation. Ignitability is improved by the V-groove cut in the center electrode parallel to the ground electrode, this directs the spark to to the edge of the center electrode thus exposing it to more of the air/fuel mixture.Quenching is reduced in much the same manner, drawing the spark to the edge of the center and ground electrodes reduces the surface area available to quench the spark.
