ACDelco Professional 9748HH Spark Plug Wire Set, 8 count (Pack of 1)

My friend bought aftermarket spark plugs wires and they were too long compared to the one I pulled off his truck. I didn't feel comfortable installing it because it has too much wires over hanging. I told him to just get the ACDelco since they were OEM and will be a better quality over the cheap off brand and will fit. The price wasn't that much more compared to aftermarket and it fits better. The quality of the ACDelco was much better as well or does not feel cheap when handling it.The ACDelco was only a little bit more so why bother with cheaper alternative with less performance and quality.

These were a perfect replacement for OEM plugs. They are working great.

I recently purchased a 2004 Tahoe Z71 and figured it could use some new wires with all the miles the previous owner racked up. I also purchased these since many other stated that once they took off the original wires, that many of them broke so I wanted to be cautious. The wires had been replaced as they were not stock and some cheap aftermarket brand. These ACDelco wires not only fit better but looked nice and OEM. So far they have performed great and I seem to have a slightly nicer idle, of course the MUCH needed new plugs (another review) I'm sure helped out tremendously. I don't see the need for purchasing anything other than the stock wires and these preform very well and the cost is much less than the "higher quality" aftermarket ones. I highly recommend these stock wires. Don't forget to use dielectric grease on the ends that go onto the spark plugs! I bought a much bigger tube than needed, oh well. Just get some small grease packs at your local parts store and use a q-tip to swab it around the inside of the boots before installing. Oh, and the worst boots to get off are of course the back two, the passenger one taking the longest. TIP: where gloves to protect from the heat shield, securely grab with hand\fingers and twist back and forth while pulling....

Keeping it ACDelco in my truck. Great and reliable product. Used them on my first tune-up..

installed these on my 2005 GMC Sierra 1500 with the 5.3. The old original wires were a massive pain to get off, but these new wires went on easily and the truck runs great again.

Great quality, but we're two inches too sort for my truck.

Excellent product, great fit will buy again.

OEM is the only way to go
