OEM spark plug wires. Don’t waste time and money on 3rd party spark plugs wires, go with what is put in at the factory.

Slightly longer than Oem on my 6.0 but not a problem, snapped in well and ran well, better than off brands that didn’t last three months

These are a perfect fit on my '05 Silverado 2500HD w/ 6.0. with square coils - coil 12558693 H6T55171ZC. These are 'slightly' longer than the OE wires and you need to reuse your existing heat shields, but the length is better than OE becasue it puts less bending strain on the wires at the plug... and the price is right.

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 muchOnly thing these plug wires are a bit longer compared to the factory OEM Delco wires I removed for my 2500 Chev

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 handfingers and twist back and forth while pulling....
