Review on 🔌 Enhance Performance with ACDelco 748RR GM Original Equipment Spark Plug Wire Set by Marc Salem

ACDelco 748RR GM Original Equipment Spark Plug Wire Set direct OEM replacement kit for my 2007 Tahoe 5.3L flex fuel engine. You'll need to re-use the original heat shields/ground shields from the old wiring harness, but that's a no-brainer as they can be easily plugged in/unplugged. They're all the same length, so you don't have to figure out which fits which fork. Be sure to listen and feel for a "click" during installation to ensure a good electrical connection so you don't get a misfire.
