The change you feel from plugs or wires is not a hp difference. It's a difference in start-up and throttle response. They will not provide more power. You could also see a change in gas mileage.

 

The only way you might see a little power difference is maybe from changing out a fouled plug, or two. Even then, it would be minimal.

How are the E3 plugs treating you? Where did you get them, and how much were they apiece? Do you think that the better gas milage you get from them (and the wires) will pay for the mod?
