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

Great Product

worked perfect for my 2002 Silverado 2500 HD 6.0

I USE THESE ON ALL MY LS SWAPS AND FACTORY INSTALLED LS ENGINES. FITS 4.8 , 5.3 , 5.7, AND 6.0

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....

Great plug wires for my swap. These are acdelco and good quality. Highly recommend these.

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

Buen precio

Replacement wire's seemed to short. Spark plug wire's too long on 5.3 just purchased Avalanche 1500 Z71. Seller's item is correct replacement.

Quality, OEM wires. I didn't know if my truck took these, or the shorter wires. Turns out it takes the shorter one, however these also fit with only an inch of slack. So it doesn't look messy or out of place. TBH, I doubt most people would even know. I'd say if you don't know which set you need, the long or the short, just get these and you'll be fine with them. My truck is a 2007, so it's on its last legs anyway.

Waste of time and money

This looks and feels exactly like original equipment. The length was the same. Were snug and fit well. Great product.

They fit and work well.

Delco quality is hard to beat, worth the extra money to buy OEM quality instead of buying cheap junk you need to replaced twice as much Only thing these plug wires are a bit longer compared to the factory OEM Delco wires I removed for my 2500 Chev
