JDC "Show Series" Coil-On-Plug Ignition System
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.
We're proud to introduce the new JDC "Show Series" Ignition systems! These systems use the same high-quality components as our standard systems, but include a newly designed solid carbon fiber mounting plate that has a better overall "show car" appearance, while still offering the same great performance! Each coil is recessed into the plate for the same overall height to the spark plugs, but there's no gap left between the coils and the plate! These systems are only available with a carbon fiber mounting plate and an optional upgrade to titanium mounting hardware.
You can choose from two mounting plate and wire harness styles:
-
"Standard" Show Kit - This mounting plate/wire harness option includes the traditional wire harness that connects on both sides of the valve cover. This is a direct fit and doesn't require any modifications to install.
- "Hideaway" Show Kit - This option includes the hideaway harness, which tucks underneath the mounting plate using precision CNC cut holes, and makes its connections behind the valve cover for a wire tucked look! This mounting plate also now covers the gap that is normally left on the passenger side valve cover area. To use this mounting plate you will need to remove the bracket on the left side that is normally used to hold the O2 sensor connector.

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!
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.
