Ahem... may I?why would you go with such a cheap brand of plugs if you have almost 8,000 dollars into your engine? Why not just have the extra benefit from a COP setup?
There are many things on the 4G63 engine that were done right. It's an under-tuned engine that has lasted for decades because of the potential built into it by Mitsubishi. One of the components they over built is the ignition system. Little or nothing has to be done to improve on what already exists. Cheap NGK plugs and OEM wires will get you to 500+ HP. COP setups are cool.
