JDC Coil-On-Plug Ignition System Refurbished Denso Coils
Refurbished coils are getting harder to source and our inventory fluctuates. If you would like to check our current stock before ordering, please email support@jdcustomsusa.com or call us at 423-665-9616. Purchasing a kit with new Denso coils is recommended since we keep those in stock at all times.
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 ignition wires and simply plugs in and bolts down! No assembly is required to replace your bad ignition coil set! 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 the cheap off-brand coils that won't perform as well or last as long.
About the Hideaway Harness Option:
- This harness uses the same high-quality connectors, military spec tefzel wire, and wire sheath as our standard COP ignition 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 plug 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.
