Review on ACDelco 746QQ Original Equipment Spark by Ahmed Jackson

The cables work fine after installation but I had trouble connecting. The caps on the ends that go over the spark plugs slide over the wire, resulting in no "click" sound when you attach the wires. I had to spend 40 minutes carefully fitting the boots. I sprayed silicone grease along the wires, pryed the boot back with a screwdriver, then pushed the boot up far enough to fully expose the end of the wire. I then used the old spark plug to adjust the ends of the wires to ensure a snug fit (pass the wire over the old spark plug about a dozen times. Finally I adjusted the boot to where it should be and the Cables installed They work as they should but the wires seem to be working very well.
