I think they are overpriced, rebadged wires. I was shopping for plug wires about 2 or 3 weeks ago, I went to Pep Boys and they had the APC wires for like $80 or $90. Their wires are way oversized, like 9 or 10mm. I think you can get wires that are as good or better for half that. I did. I got some Accel Thundersport wires for $45 from Pep Boys.
