overall very good product
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.

Spark 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.

Fit
by Bryan from Big Lake, Minnesota on May 15, 2012
Replaced on 89 3.0L Mercruiser. Picture shows they are yellow, but I received blue ones. Like the blue color either way, and they fit well.

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!

Bad fit
by Robert from Rainier, Oregon on June 15, 2014
The quality of the plug wires is good, however I had to bend the clips for them to stay on the distributor cap and the boots do not cover or attach in any fashion to the distributor cap. These were purchased for a Marine environment, a boat that is in the salt water a lot. Now I need to remove them on probably a monthly basis and clean and apply silicone to the distributor so it does not corrode. This creates another step to take prior to running the boat each time.

Perfect
by Chris from Pinckney, Michigan on August 13, 2012
These wires fit perfectly. All the lengths were correct which made installation a breeze. I have purchased other branded wire sets and that was not the case. This is an outstanding, well built and engineered product.
