Spark plug wires

[cdf1271]

Hi all,

Wondering what kind of spark plug wires everyone is running and had good luck with. I just recently had some of the ford performance wires that started misfiring after only around 6k miles and a couple years. I put back on my original factory wires and now it's good again. However, im not sure i how long i want to roll around with nearly 25 yo wires .

Thank you for any input.

OEM Motorcraft have worked great for me.

Just get OEM Motorcraft wires. I had bad FRPP wires too.

The old school FRPP wires were great, but that was years ago.

I'm actually looking at doing plugs and wires myself to hopefully take care of a slight sputtering issue under load at lower rpm's. I've searched the forums and have heard decent things about the stock Motorcraft wires and Autolite 764 plugs. I was going to order these from Rock Auto:

Not to hijack the thread, but are Autolite 104 interchangeable with Autolite 764? My local store only carries the 104 and it shows that they fit my car. Is there anything different about these I should know about?

104 has more threads, 764 has like half as many (like 5). I used 104s and they're fine. Overall plug dimensions are basically the same. Search Google for a pic of each and you'll see the difference in the thread count. Not sure how many threads there are in the cylinder head, but if there are more than the 5 or so the 764 plug has I'd rather run the 104 anyways.

I have the original red Ford Racing 9mm wires on my 94… Never had an issue with the Ford wires.

I actually had good luck with them too. Both on the 5.0 HO and 4.6 4v

Just don't try to replace them with NEW Ford Racing wires.

+1 or at least if you do, don't be surprised if you experience problems.

NGK or Motorcraft.

I used to run Taylor Spiro Pro 8mm. Switched to NGK, maybe placebo, but it felt like the engine ran better. The Taylor's were maybe 2 years old.
