Review for Sierra 18-8800 Wire Lead Kit by a CustomerJune 23, 2009
Well what can I say other then they look good... The coil wire rubber on the coil is rather small and hard to get on the coil....

overall very good product by Robert - Nashville, TennesseeSeptember 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 - Trenton, OntarioJuly 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.
