The one I’m holding in the pic (for cylinder 3, it seems that terminal is more slanted which requires a longer wire), is one I had to reuse. The new ones are too short (about 10″ and my old ones were 12″-13″) for that particular one and idk why. The instructions say to compare the old to the new to put the correct lengths in each spot but the new ones are literally all the exact same length! I measured and remeasured and it made no difference. Otherwise they click nicely into place at the terminal, I wish they had sent boot covers as well, mine are a bit chewed. I test drove the ol girl after and she runs smooth and strong again.

I own a 2002 Chevrolet Suburban 5.3 with 98,000 miles. I have the round coils part number ending in 5218. I purchased the 9748GG wire set. They fit exactly as the OEM wires that came from GM. The wires came in an ACDelco box and also were stamped on the wire ACDelco. I also replaced the spark plugs with ACDelco 41-962 platinum. The whole process took me about 1.5 hours. The plugs were pre-gap at .040 and I checked each one. I applied anti-seize to the plugs and Dielectric to both ends of the wires. The vehicle runs like new, but then again it ran great before I installed these new parts. It was time because the plugs were starting to rust. I owe making the correct decision on the parts I purchased to all the prior reviews on this page. Thanks to all of you for your guidance.

These were OEM and exactly like the stock wires I replaced. I replaced the wires on both an 01 Yukon and an 03 Tahoe with 5.3 engine’s and have had no issues. I would definitely order them again. The price was much better than in town shops even with their online discounts. Great product.

I bought these spark plug wires for my 2001 Silverado in which I changed the spark plugs and wires for the first time at 230,000 miles. I bought the new platinum double-tip plugs on Amazon too. With the new spark plugs and these new wires, my truck is running like new. Prior to the change, I motor had developed a bit of a rough idle on cold starts. In my case, this change corrected the problem 100%. The old plugs were worn out. As a lifelong car DIY person, I appreciate the high quality of these ACDelco spark plug cables. They are very sophisticated compared to old school spark plugs and spark plug cables. The current cars all have high energy ignition systems, and the plugs and cables are much better than the old school versions. The connectors to the coil, and to the plug, are very sophisticated and good. One thing to note is that you will see two sets offered under different part numbers. This set ACDelco 9748GG is made for the particular ignition coils that are on my truck. The other set you will see is an ACDelco set with a part number ending in HH. The Amazon descriptions for these two options are clear in the part descriptions. The ad tells you which coil design the cables fit. The ad tells you to check the coils on your car. The two types of coils are marked with different numbers branded into the side of the coil. The number on the side of my coils corresponded to ACDelco 9748GG. When I got them, I installed all 8 in less than a half hour. Now, if you have read forums or You Tube videos about how to replace the plugs and cables, it sounds like a hard job. It is until you understand what I am going to say. The spark plugs install normally. A technical service bulletin from GM currently recommends a little anti-seize compound on the leading threads next to, but NOT on the electrode tip of the plug. To install the spark plug cables, you insert the boot into the cylinder shaped heat shield, and put a rice-size amount of dielectric grease in the opening to the boot. With a small screwdriver or Q-tip with cotton cut off, use the stick to wipe the dielectric grease around the inside of the rubber opening of the boot, from the tip to the metal that connects to the spark plug. This helps prevent the boot from seizing to the spark plug, and it helps prevent the high energy current from arcing outside the spark plug from the tip to the threaded base, rather than the energy going through the plug as it should. You need to use dielectric grease as described. So, the boot goes inside the heat shield, and the greased boot goes over the spark plug. There is a metal connector in the boot that attaches to the tip of the spark plug. It is a very gentle and quiet click. You won’t think you have them on, because the boot will still wiggle, but I guarantee if you hear or feel the click, they are on there with strong connection. The end of the cable that connects to the coil gets no grease. It pushes up onto an opening in the bottom of the coil, and you will hear and feel a conspicuous double click. I put my coil ends on first because they are a little harder to push, then turn the wire/coil connector so the wire faces straight down, and then the heat shield/spark plug good over the spark plug and wiggle and push until I hear of real a subtle click. This is all reinstall information. The initial removal can be a nightmare, but I figured out the problem. The rubber spark plug boot seizes to the spark plug body, and the metal connector to the spark plug tip might be aged, corroded, and tight. After days of wiggling and pulling like the forums and You Tube videos show, mine finally came off. However, now that I understand the problem, there is a better way. I have an automotive pick set. One has a 90 degree bend on the end. It will push in between the heat shield and rubber boot. Then you get into the end of the rubber boot, you can turn the end of the pick to grab the end of the rubber boot. By working that pick around the end of the rubber boot, and breaking the hold of the seized spark plug boot, wiggling and pulling will release the spark plug tip connection with little effort. This pick method, when you grab the end of the boot and pull, you are essentially pushing the boot the direction it needs to go, and it breaks loose. Pulling on the wires damages them, so this pick method that pushes is the proper choice. I haven’t found anything else that will get in there to release that seized boot from the spark plug without wiggling and pulling for a couple of days each, or pulling on and ruining the wires. Having said all this, putting new spark plug cables on is a good choice, so you can save yourself time and agony by just ripping the only ones off, but save the heat shields for reuse. That’s enough on that topic. These new spark plug cables are awesome, and working perfectly, every bit as good or better than what came on my car and lasted 230,000 miles!

Wires were a good product and was said to fit my truck, but Gm apparently changed coil packs part way through production and these wires were aprox. 1″ to short ( no fault of wire manufacturer ) If in doubt of coil part # go with ACDelco # 9748HH, These are 1″+ longer and fit perfect.
I returned the first box without any problems and re ordered the right one,s. Great experience dealing with Amazon
Amazon Customer –
Ordered these and they ware too short
Amazon Page Said they would fit
Well turns out there’s two types of coil packs Round (19005218) and Square type (12558693) this is important to know I guess it does say on the product page for coils stamped 19005218 but to the average consumer they should just specify, coil Lengths are
9.3 for Round or 10.5 for Square hope this helps someone
Amazon Customer –
Seem to be working good so far they fit perfect just have to make sure you get the right length for your engine. Going by where your coil packs are and Design
MITiger –
Good match to previous OEM wires and are performing well so far
Rod M. –
See in Photo attached the Stock GM Wire from a 2006 Chevy 5.3 Note that the kit that was said to be an exact fit wires are TOO SHORT to fit on engine. ACDelco Professional 9748GG Spark Plug Wire Set
said on Amazon that it will fit BUT NO it will Not Fit. Waste of Money and should not buy parts on line.
Not Happy with Seller and Product not being correct. Longer would be better than too short.
Jenna –
Those cables are short for Hummer H2 2006 and it’s better to get longer ones 10.5 inches/more.
As the cables likely to come out at any time.
Update 21 Mar 2025
After 1 year and 9 months of use out of 8 cables, 3 are corroded.
