🔌 ACDelco GM OE 746T Spark Plug Wire Set with Original Equipment Review

I tried cheap spark plug leads on this 4.3 engine and they looked like Aura Borealis at night. For some reason this motor only wants to run on AC/Delco!

ACDelco makes it again. Great set of plug cords at a great Revain price. Very high quality and durable product. I installed it 2 years ago and it still works. These aren't the cheap useless cables you buy at the parts store. That's what GM uses for its vehicles. You will not be disappointed.

All Wiring Required for Replacement. All wires are custom made for each cylinder but are not marked. If you're lucky you'll replace the OEM kit and be able to adjust the length for each cylinder. Supplied with a small bag of dielectric grease and instructions. Apparently non-original plugs cause problems. I replaced the original OEM wires with a 1997 (18 year old) Blazer with 148,000 miles. The car ran well and the original cables far exceeded the recommended replacement interval.

These wires were basically in good condition for about 2 years then the coil wire failed. "Lifetime" guarantee is almost non-existent. Revane is directing me to AC Delco. AC Delco directs me to Revane. All other auto parts stores I have dealt with cover auto parts warranty but in this case Revain refused to cover it as it was over 30 days from purchase. These wires may or may not last for you. However, after 30 days you are on your own. It's better to get them from a store that actually stands…

These cables failed on 10/2020 after almost six years of use. I remember when I bought them they were a bit shorter than the wires originally installed and needed some stretching to fit. At the time I was wondering if I really got the more expensive OEM line (746T) or if it had been replaced by the cheaper Pro line (9746T). It's hard to tell as the part number isn't on the cable itself. I recently looked into this again after removing the wires and I think I got cheaper wires than I originally…
