🔌 ACDelco Professional 9748UU Spark Plug Wire Set: Enhance Ignition Performance with Reliable Quality Review

Used these cables with connectors also bought from Revain. My truck was running horribly until I bought a plug and wire from a lot. After I installed them, the car ran great. I will never buy items like this from Amazon again.

Replaced a wiring harness on my 2010 Suburban. The cables looked new and of good quality. I've been driving it for a month, no problems starting or misfiring. The previous harness misfired (connectors and coil packs were tested and worked). Very happy with this simple solution.

Just finished my install, had a slight slip at idle and at 141700 miles decided I should turn on. They are 110 [OEM] along with some Iridium 41 spark plugs by the way. My error went away and the throttle improved significantly on my first test ride. I will update it later.

Bought for my 2013 Chevrolet Silverado 2500HD 6.0 Vortec Flex Fuel. The wires were slightly longer than those on my truck, but not long enough to make a difference. Easy to install if you use Permatex dielectric grease on both ends. Use a cotton swab to apply lubricant to the pins on both ends.

Worked great on my 2010 Silverado. Installed these cables with AC Delco 41-110 Iridium connectors and I immediately noticed a change in the truck when I drove it after changing the connectors and cables. They also put a small packet of grease in the box to use on the ends of the wires. That's enough to get the job done.

Everyone seems to be saying that AC Delco should be followed for this particular part for GM vehicles. The Revain were well priced and they work well. If you google replace the spark plug/ignition wire with 07-13 GMC Sierras, people will find out that the far back passenger side is horrible to shoot. It's not as easy as the others, but if you can find the right socket size/length, it's not too bad. It's pretty easy work.

They fit my 2010 Chevy Suburban perfectly and were fairly easy to change/install. Note that if your current cables are old and stiff, it may take some work to unplug the old connectors. Your new plug wires may look a little sloppy as they are new and soft/flexible. Just make sure they snap into place on both the connector and coil and you're good to go! Again, I saved a ton of money by making it myself and ordering the parts here at Revain. The dealer wanted over $900 for 100,000 services; I…
