Ok for the money they are a good deal but my goodness these wires are super long, make sure you have extra wire looms and zip ties.. I guess it's better than being to short but they look good.

All the wires except the wire from the coil to the distributor fit fine for MerCruiser but It takes a special boot on the coil, which was not provided. Also dielectric grease was not provided. You must get that at the local auto parts store.Fast delivery

Just wish it was Vehicle Specific..You get 4 sets of 2 wires..Different length. And I ended up with an extra..They fit good on a Chevy 350 with Headers and AC plugs.
