plugs and coils
I'm very new to the modular 4.6. I have a 01 gt with some exhaust work and a cold air intake. I'm looking to do some performance improvements that are inexpensive, I have a budget and the budget is called the wife!!!!!! I was thinking of starting with plugs and coils, I just don't know what is preferred and what will work best. It is a daily driver so I can't go with anything that is too radical and will do more harm than good. Any help would be greatly appreciated.
