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

This system utilizes R35 GT-R ignition coils to withstand upwards of 1000+ horsepower without needing a pesky CDI box! The stock Hitachi coils on the GT-R are known to handle 1000whp+ without needing an upgrade! 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 a year 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 1000whp! Forget the need for a problematic CDI system. This COP System can do it all!

Introducing our new ‘Hideaway” wire harness!

This harness uses the same high quality connectors, military spec tefzel wire, and wire sheath as our standard COP wire harness, but this one hides under the mounting plate for a super clean, wire tucked look! This harness offers the same quality and performance as you’d expect from any product offered by JD Customs USA. This harness is sold separately, or can be added to any of our ignition system options for an additional $50.

How is this harness different?

Both leads come out from the valve cover on the right side and are concealed by a single wire sheath. The right side connector makes its hidden connection behind the thermostat housing and the left side lead can be ran under or over the intake manifold to make its connection behind the valve cover for another hidden connection.

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.
