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. 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.

  • Pre-gapped for optimum performance on nitrous, turbo and supercharged applications
  • Heat range designed specifically for nitrous, turbo and supercharged applications
  • Excellent thermal dissipation for improved resistance to detonation
