Zex Nitrous Oxide Systems 82003-8 Spark Plug

ZEX engineers realized early on that factory style spark plug designs are very prone to detonation in nitrous and forced induction engines. Factory style spark plugs tend to have a high heat range and a long ground strap. This is fine for stock combustion pressures and temperatures, but it is very dangerous in a nitrous or forced induction performance engine. Under nitrous use or boost, factory style spark plugs tend to overheat in just a few seconds. This overheating causes the spark plug ground strap and center electrode to turn into a glow plug. This condition causes air and fuel in the combustion chamber to pre-ignite and detonate, causing engine damage.

HYPERFORMANCE SPARK PLUGS
ZEX is the only nitrous system manufacturer with specific spark plugs manufactured for the unique requirements that nitrous and forced induction engines have. ZEX Hyperformance spark plugs have an optimal heat range and ground strap design that maximizes the safety and performance of your nitrous or forced induction engine.

POWER TUNE / POWER RACER SPARK PLUGS
Average plugs rely only on their designed heat range to keep them from fouling. While this is fine for the narrow operating range of stock engines, its not the best choice for modified, high-performance engines. ZEX developed Clean Fire Technology which not only uses an optimized heat range, but also uses spark from three side-gapped ground straps to super clean the center electrode. This maximizes available ignition power and ensures dependable performance.

When you look at all this new plug technology, its clear ZEX has a better choice for those serious about performance. Two different plugs have been developed with optimized heat ranges for the specific modifications and power levels you have. For engines with bolt-on performance parts and computer tuning, up to 400hp, our Power Tune Plug is ideal. For those engines with nitrous, blowers, or turbos, our Power Racer Plug will maximize performance in engines up to 700hp.
