We price match!

The STM Coil-On-Plug (COP) Ignition System for the MIVEC Evo 9 is a direct replacement to your factory coils and wires and simply plugs in and bolts down! This piece will fit under your factory spark cover, or you can leave it open to breathe and stay cool.

Vehicle Fitment:
2006 Mitsubishi Evolution IX
• Plug and play, no tuning required

• We offer these kits in a few different styles for Evo 9 and Evo 4-8. See More COP Options

Shipping Times: 2-4 Weeks
These COP kits are hand assembled and recently we've been waiting on components for them to be completed. Accounting for build and wait time, these kits typically ship in 2-4 weeks, sometimes sooner!

Install Notes:
Make sure you replace the included 15A fuse in the fuse box on the driver side under the dash. The ignition puts out more power than the factory 10A fuse can handle and it will eventually pop and your car will not start if it does. It is located from the driver seat by your left knee in the interior fuse box, top left, red fuse, #1 position.
