Possibly dumb question, but I have spent way tooo much on my engines and i am trying to find any way I can to save a few bucks...

Is there any 8 cylinder plug wire set that will fit into the mercruiser 3.7 4 cylinder engine? I ask this because I have twin engines and I always need to buy 2 sets...

Or does anyone know an Autozone brand like a Duralast plug wire set that will fit this engine?

Thanks!

something from the 70`s would fit the dist and plugs. the 470 dist cap needs wires that go in ,not on the cap.

I tried that a few days ago and got wires for a 79 Chevy Nova, although they fit and worked, they weren't long enough to wrap around nicely so I had to return them. The workers at my local Autozone are not very knowledgeable when it comes to anything when it comes to auto parts. They needs a specific make and model or a part number so they can look it up in their computer. They cant help any other way.

Napa has 470 plug wires for about $20 belden brand. I think they work fine. They fit perfect. My local napa had them in stock. They were specific for the 470. Its my first year on them so I can't speek for longevity. A 8 cylinder set will leave you short a coil to center wire with twins
