I have Magnecor wires and NGK plugs, and I would not sell them for $$ if I could. I'm no auto tech, but by having the wires... I feel safe that my mods (which help the car breathe) should benefit from the better spark. I'm sure aftermarket wires last longer as long as moisture doesn't get in. NGK wires are blue.scrubaru said:I have a 00' RS and I wanted to change the plugs and the wiring. I wanted to know what Brand of plugs people were using as well as wiring. Not that it's important but I'd like to be able to get colored wires, preferably blue. thanks in advance.
