Review on Edelbrock 22716 Sleeves Resistance Performance by Gregory Shorunov

Bought for other ignition work on my 2007 Tahoe 5.3L. It was time to tune in as my truck was giving out CEL PO301 codes here and there. I thought the truck was approaching 188k and the previous wires and connectors were almost 90-100k. I purchased this wire set along with NGK Iridium plugs and Red High Performance coils. The wires are a bit longer than the high power ACDelcos I've had before, but this was perfect as my new coils required longer wires. Took me about 1.5 hours to install all 8. I am very impressed that the truck was set on fire immediately and nothing more. misfires. I sat in the truck for a while to see if I could feel the misfire vibration. Vibrations are very minimal and practically gone, and the 5.3 LS V8 engine feels natural again. The test drive was great so time will tell if all of these parts hold up and perform as advertised by their manufacturers. We'll see and I'll update you later in the future. (no pun intended)
