Zex Power Racer Spark Plugs

More Spark, More Power. When you add performance modifications to your Pony like nitrous, blowers, or turbos, you need a stronger spark to maximize the horsepower benefits available from these modifications. That is where Zex "Power Racer" Spark Plugs come into play, these plugs will maximize performance in engines up to 700hp.

Nickel Coated Copper Core. ZEX™ has developed "Igniter Core Technology", which puts a copper core inside the nickel ground strap. Copper conducts electricity and heat over 4X better than nickel alone, with this unique hybrid design, you get copper’s incredible electrical and thermal properties, for optimum spark and heat transfer, yet still retain a nickel shell for long life and durability. It is truly the best of both worlds.
