    Beautiful appearance and fantastic performance at a fair price. Second boat with 496HO that Ive used these wires on. Refreshing to receive a product that exceeds expectations for a change.

    496 Marine Spark Plug Wire Set

    I wanted to try these wires out for a couple of months before writing a review on them. These are excellent wires and I have noticed a major improvement in my engine performance as well as fuel mileage by switching to these wires from my stock wires. The fit and quality is excellent!

    496 Mag HO Wires

    Posted by Mark on Nov 4th 2020

    Best spark plug wires I've ever bought. Fit, finish, test and actual use are the best I have ever seen. I tested on my starboard engine and will now buy them for the port engine. The wires are a beast!

    496 Mag HO Wires

    Posted by Mark McGahey on Oct 28th 2020

    I bought a set for my starboard engine to see how good they were. These things are top shelf and come in an array of colors. They are very heavy with top quality ends. I tested the resistance myself and they are as advertised. I expect them to out perform the factory wires and will be purchasing another set for the port engine. These are probably some of the best if not the BEST wires I have ever purchased and I have tried all the big brands. The owner actually called and talked to me when I asked a question online about his wires for the 496 Mag HO. VERY IMPRESSED! Extremely satisfied customer here!

    So far so good. I just installed them. Heavy duty wires. Far superior then the OEC brand.
