with any one how like this bad ass monster
curently pretty much stock
cold air intake straight exhaust pipe (no cat) roh 5 star 245/225
going to put accel performance wires and coil i wonder if it will make some extra horses
if it does add any horsepower (which I doubt), you probably won't notice it, aside from it looking nice under the hood. I would suggest going for something else first, wires and a coil would be one of the last things I would do. A chip would probably be the best bang for the buck if you can find one.
