PJ5,I was just at your stie...looks great... out of curiosity...I saw the shaved VW, and I love that look...how much would it cost to do the door handles only?
I got the wires too. It dramatically improved the smoothness in acceleration. Standing starts are much easier for me now. I can feel more power especially in the low-rpm ranges.
I haven't been keeping track of fuel economy so i can't really say. However, there haven't been too many posts from people who've bought the wires and were unhappy. It's a good bang for the back mod that you will notice right away. Install was a snap too.
It looks like engine wiring is a cheap way to improve the driveability of your car. I think my next mod will be some upgraded ground wires.
