    Rated 5 out of 5 by from Great Product Brought this for my son's F Body 305. The wires were plenty long enough to go over valve cover with a lot left over.

    Rated 5 out of 5 by from Quality, good looking, easy to install Just installed these spark plug wires on looms and they look great and much more organized. The yellow color contrasts nicely with the Chevy orange and really stands out. Would have liked to have had some instructions as I had never installed custom length wires but 10 minutes on YouTube solved that. Excellent quality, all parts included. Very happy.
