Spark plug wires

[DavidT]

lol so what's the deal with motorcraft wr4021? Rock auto lists it as a sho replacement. But there's no boot that fits and seals the spark plug well...

MTX is WR4033
ATX is WR4081

If you are looking for OEM wires, contact Shosource. I have also seen a sets on ebay from time to time. They also have other options on their site

I found out the hard way about those. I have a set sitting here and have no idea what they're for. I guess the Vulcan motor? Since I needed a set quick I got some omnisparks from O'Reillys that have been fine.

I've had success (and failure) with rockauto plug wires. The napa/belden 700771 are correct from my experience. I haven't had failure, yet, and they fit properly. Message me if you need more help finding a set.

I had bad luck with the Belden brand but they did exchange them with no problem.
Mine had spark jump that you could easily see at night.

I have had good luck with all other brands that I have tried, including a low budget brand called X act from Auto Zone that were around $50.00, and had the correct ends and sealed well.

I'm on my 2nd set of Delco wires, and have had great success! They're not as cheap as when they first came out, but still a goid value.
