Great price on a high quality item
by Brandon from Murray, Kentucky on June 02, 2014
My boat runs smooth with these wires, they have a high performance look (electric blue) and fit perfectly. Do take note that one side of the cable is specifically made for the cap and the other for the plug I did have to reverse a few. The wires are thicker than stock (a good thing in my opinion) so they won't really fit through the retainers but that didn't matter much to me. Definitely would purchase again!
