I had a set of moroso wires and hated them, too much EMI. I heard loud pops constantly on the factory Concert Sound II, and who knows how that affected the ecm. I switched to Magnecor 10mm wires and no more pops. As far as peformance goes, I can't say since I did a lot of other stuff to my turbo-t on the same weekend as the wire switch. jmho
magnecors are red, btw
