Picked up a set of these, and tossed them on the car this morning. My right arm isn't happy, as it's TIGHT in there to do anything. But, other than cursing the tight space, it was an easy in n out. Red looks pretty. (There are 4 wires, just couldn't quite squeeze my camera in there for the correct angle to get em all in)

You feelin any kinda of difference in the motor? Does she seem to be runnin smoother or is it more like a color upgrade?

I've only driven around the block a few times to make sure everything was connected securely/correctly. I really doubt there will be much of a difference, to be honest. The weak part of the ignition system are the coils. Maybe some noise/interference reduction is about all I'm expecting.
