Features & Benefits

  • Coils feature advanced bobbin technology with highly specialized silicone magnetic steel cores
  • Optimized coil design yields at least 10-15 per cent more energy available for the spark than the most common OEM coils.
  • Specialized high temperature epoxy resists shock and vibration while increasing thermal conductivity
  • Coils offer a direct performance bolt on upgrade
  • Limited 90 Day Warranty

Direct OEM replacement form factor and connections means simple installation. Available individually or in sets of 8


Late model Coil-on-Plug/Coil Near Plug series are optimized to improve the spark capabilities of late model ignition systems. Coils are epoxy molded to prevent premature failure from moisture or winding fatigue. Superchargers, turbo chargers, and nitrous all increase the demand on the ignition system. Whether it's a performance application with add-ons or an increase in power for the stock ignition, Flame Thrower coils won't disappoint.
