    Rated 5 out of 5 by from Had good luck using MSD prior. I’m happy with this It’s so much easier purchasing what I want through you rather than a local box store. Came in faster than I thought it would.

    Rated 5 out of 5 by from Msd products are awesome. I have tried running my wires under the headers. I kept burning the same 2 wires. With cut to length wires and jegs aluminum wire holder the engine and bay looks clean and should not burn any more wires. This is the best that I have made the wires look and be functional
