Review on 🔌 ACDelco Professional 9748RR Spark Plug Wire Set: Optimal Performance and Durability by Brandon Garrett

Good quality and great job for 2007 Tahoe LT. This is a factory wiring harness for replacing spark plugs. High quality cable connectors at an affordable price. My truck runs smoothly. I have always used an ACDelco 9748RR spark plug wire set and an ACDelco 41-110 Iridium spark plug. Please note that do not disconnect or remove the spark plug wire after installation, otherwise damage may occur. You will also need dielectric grease for tuning and tools.
