Product Details

The Plasma Spark is the spark plug boot (socket) specially designed and developed to work as a secondary amplifier.

It creates strong sparks in a very short time (nano-seconds); creating a faster flame front and quicker light-off of the mixture kernel to complete combustion. After installing the Plasma Spark, you will feel immediate torque gain in the low RPM range, and more horsepower in the high RMP range. 

Installation is also easy, direct bolt-in to the engine, no splicing or cutting into stock wiring. Simply replace the stock boots with our Plasma Spark Boots and ready to go! 


  • Creates a strong spark in very short time.
  • Creates ultra-fast spark discharge.
  • Easy installation.
  • Compatible with all OEM component.
  • Compatible with OBD-II. (On-Board-Diagnostics)
  • Compatible with Plasma Direct coils.
