View Full Version : Question regarding plug wires
OK, so I've never been happy with the plug wires that came with my engine, and the way they had to be routed. One of my winter projects is going to be to buy some bulk wire and fabricate a new set of wires that are cleaner looking.
Not familiar on what would be the best type of product, but one I'm looking at lists the following. Spiral bound suppression core, 500 ohms resistance per foot, silicone insulated, and 8mm width. Will wires that meet these requirements work for my 331 with EFI stack injection?

Most good 8mm wires will do what you want.
I run the Taylor 409, 10mm wires, probably overkill. Bought the set with the molded sparkplug ends. Taylor has a few different angles for the plug boots, I'm using the 135s. Built the distributor connectors for the custom fit.

I'd agree with Jim.
I would just add that any high EMI suppression / resistor type wire should do the trick for EFI.
Thanks for the info guys.

You might look at these (https://www.summitracing.com/search/part-type/spark-plug-wire-sets?fr=part-type&SortBy=BestKeywordMatch&SortOrder=Ascending&keyword=M-12259-M302), good quality at a fair price. As an added bonus they're numbered which is nice.
I'm actually looking to cut my own lengths. I already have a pre-cut set and the lengths don't work. I mean they work, but the way you have to route them makes them look really bad.

The Ford wires are cut to length.

Ford wires are too long for me too. I think the 302 set is made to fit the 351 also, thus the length.
