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.

The STM Coil-On-Plug Ignition System is USA-Made with genuine Denso ignition coils and features a waterproof harness constructed from military grade Tefzel Teflon wire, Stay-Clean wire sheathing and a thick, carbon fiber mounting plate with stainless and aluminum hardware.

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.
