ACCEL 170081 Pro Sleeve Fiberglass Spark Plug Boot Guard - Pack of 8
The Accel Pro Sleeve Spark Plug Boot Guard features a double-layered fiberglass boot guard. It takes the heat and abrasion instead of the boot. An adjustable ring allows the boot guard to be rotated, which results in a longer lifespan. The material expands and stretches over irregular surfaces and is easy to install.
