NGK 4177 V POWER SPARK PLUGS TR6 SET of 8 ONE HEAT RANGE COLDER THAN STOCK

NGK TR6 V-Power Spark Plugs (Set of 8) 

Replace your stock plugs with these NGK TR-6 Plugs, there are one step colder than stock. These are a must when changing out your supercharger pulley to create more boost. The colder plug will help prevent detonation from the increased heat the motor see's from higher boost levels.

These NGK V-Power spark plugs offer economical performance for nearly any automotive application, and are the only plugs with NGK's V-Groove technology. They enhance ignitability, lower the voltage requirement of ignition systems, and have strong anti-fouling characteristics, while improving fuel mileage and acceleration performance. The V-Power plugs also are highly durable against electrical and chemical wear, making them a long-life replacement plug. Because of the V-Groove, the spark occurs at the edge of the center electrode. So heat is not absorbed by the electrode itself. This allows the flame kernel to expand quickly and efficiently for a complete burn and great performance.
