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

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....

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

worked perfect for my 2002 Silverado 2500 HD 6.0

Install went well. Price and fast delivery.

Fit longer wires on 2005 2500HD 6.0

Good quality but disappointed they are made in china now . Used these on my 2005 Yukon 5.3 . Identical to my original

Great product for half the price. ACDelco product. Ordered the regular and got the gold brand wires. ACDeco stamped on each wire. Will definitely buy again when needed.

Good quality. Almost like the original cables, but about 1" longer. They still work, you just need to make sure you route them so they don't contact anything. (I have a 2004 Chevy Tahoe with the 5.3L engine)

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.

De bastante calidad

Waste of time and money

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

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