More Info:
The STM Coil-On-Plug Ignition System is USA-Made with genuine GTR NGK 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.

This ignition is designed for modified builds from 400 to 800 HP. Designed for use with the stock ECU and is also compatible with AEM EMS V1 & V2, Haltech, MegaSquirt and the SunAuto Hyperforce. This system will NOT work with CDI boxes or the HKS DLI.

Tuning will be required with the GTR coils. You cannot just swap these in and drive normally. It's recommended to install this ignition on the dyno with your tuner.

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.
