Introducing the JDC Premium Coil-on-Plug Ignition System!

This system utilizes authentic Hitachi R35 GT-R ignition coils to withstand upwards of 1100+ horsepower without needing a CDI box! The OEM Hitachi coils on the 2009+ GT-R are known to handle 1700+whp! This system will plug straight into your factory wire harness without any modifications. It's a simple, 10 minute installation.

Are they reliable?

These systems have been tested on multiple Evo's for over three years and show great reliability as well as performance. The JDC Premium Ignition System is the only ignition system your Evo will need throughout its entire lifespan, starting with bolt-ons all the way up to a drag car pushing 1100+whp! Forget the need for a problematic CDI system. This COP System can do it all!

Warranty Information:

  • Coils- 3 years
  • Wire harness & mounting plate- lifetime
  • Warranty only applies to the original buyer and is non-transferable 

Tuning Notes:

  • We suggest setting the factory dwell time at 3.4ms @14v to help keep the coils cool.
  • These upgraded coils can support up to 4.5ms which would allow you to run an even larger spark plug gap for better combustion, which could support even more horsepower.
  • For example, 3.0ms @14v has easily supported 870whp on a mustang dyno.
  • Saturation that could shorten the life of the coils and cause premature failure would be around 5.5ms @14v.
  • For high power builds a .014 - .018 spark plug gap may be sufficient, but will vary depending on your individual vehicle.
