2003 Hummer H2

2003 Hummer H2 Nology Capacitor Spark Plug Wires

These wires are the most technologically advanced ignition wires available. They create the hottest, most powerful spark possible. They are engineered with a unique built in capacitor that allows energy from the ignition coil to accumulate until the voltage reaches the ionization point. At that moment, the entire power of the stored spark is discharged at once. Combustion is faster and more complete, resulting in increased power and a more complete burn.

Part# 400-380    2003 Hummer H2 Nology Spark Plug Wires                     $299.00
