by Robert from Nashville, Tennessee on September 24, 2012
Product arrived and was as advertised. Overall very good quality. Good solid connection to spark plugs. Coil wire was hard to make stay on center post of distributor cap. Otherwise I would give it a 5. Would definitely buy again.

Full StarFull StarFull StarFull StarFull StarSpark Plug Wire Set - Mercruiser 120
by Jason from Trenton, Ontario on July 08, 2012
I have been using these wires now for the past month, about 40 hours or so and they seem to work great. No problems with miss fires, they snap on easily and hold tight to distributor and spark plugs as they were designed. If I had to change anything it would be the lengths. The set I replaced had better lengths for each plug, especially the shorter ones, which could be a bit shorter. I suppose they're designed for a variety of different engines as well, one size fits most. It's not a deal breaker at all. Very satisfied nevertheless. I will be using the same wires again for any replacements I do in the future.

Full StarFull StarFull StarFull StarEmpty StarAn improvement to performance
by Jami from Gulf Breeze, Florida on September 29, 2011
I replaced a pretty worn out set of OEM wires on my 470, thinking I wasn't going to see an improvement. Was I wrong. The engine jumps to life instantly, as opposed to taking several revolutions. They fit fine, too. The distributor side of the spark plug wires are 90s but the picture shows straight. It's not that the 90 degree boots won't work, but the OEM are straight and it is just a tidier installation. Also, the the boot for the coil isn't big enough.

Full StarFull StarFull StarFull StarFull StarGreat 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!
