Suffering from spark blowout issues on your underpowered OEM coils? The JDC Ignition System is what you need! The JDC Coil-On-Plug Ignition System is a direct replacement to your factory Evolution 4-9 coils and wires and simply plugs in and bolts down! No assembly required! Simply remove the setup from the box and install it on the car. This system utilizes 100% authentic high performance, Japanese made Denso Ignition Coils, not cheap off-brand coils that won't perform as well or last as long.

The JDC Coil-On-Plug Ignition System is made in the USA. These systems are guaranteed to perform the same as SparkTech/ Spoolin' Up non-CDI systems! The JDC systems have been on the market since 2015 and have proven to be one of the best performing and reliable systems out there!

  • Works with all Evo 4-9 USDM/JDM models (select the correct option according to the valve cover you have. Evo 9 with MIVEC is different than Evo 4-8.)

About the Hideaway Harness Option:

  • 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 $30. 

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 run under or over the intake manifold to make its connection behind the valve cover for another hidden connection.

Installation Instructions:

Titanium:
  • Titanium mounting plates will come standard with our burnt finish. To request a certain color please email us before purchasing. Please make sure to only clean them with Windex and a microfiber towel or a Clorox wipe. Harsh chemicals and polishes may tarnish or remove the colored finish. 

Warranty Information:

  • Coils- 3 years
  • Wire harness & mounting plate- Lifetime
  • Warranty only applies to the original buyer and is non-transferable 
  • Warranty does not cover water damages or any other abnormal issues due to improper maintenance or care.
