I didn’t realize how bad my engine was running until I put these coil packs and plug cables on. My truck runs like a new vehicle!

good comments

I installed these on my 2005 Suburban with the 5.3 engine while installing new heads. My truck has 225k on the original coil packs, wires and plugs, so I figured it was time to replace them while I had it torn down. Unfortunately, it turned out that there was something much more wrong with my engine than just the heads. I will be installing these on the new engine that I have on order, and updating this review. I can say that they really do dress up the engine compartment though.
