🔌 ACDelco Professional 9748HH Spark Plug Wire Set: Enhanced Performance and Durability Review

Item appears to be fine. They don't seem to make much of a strong bond. There is no spring or anything like that in the plug, so you can tell there is play by turning the spark plug. Nonetheless, they fit and my truck seems to be running fine. The 2001 Chevy Suburban 5.3L 9748 HH was perfect. Just make sure you hear a click when you click it. The first one I did I thought I had it all the way. But the second I cried and it clicked. Went back to the first and sure enough, it clicked.

These have been well received and are genuine AC DELCO quality but be sure to consider this before purchasing. These "HH" models are longer.

I realized they were the right length after realizing they were 10.5" long wires. I did notice that the GG wires were shorter compared to the jumper. These wires fit well and the Metal spark plug boots fit snugly.The wires can be painful but I spoke to the mechanic and he told me to twist the rubber end of the boot to break the connection with the spark plug…

These cables fit without any problems. They were a little long, but better a little long than too short. I read in one of the reviews that this car has 2 sets of cables because there are 2 different coils.
