Review on Heatshield Products Thermaflect Sleeve - High Performance 2-inch ID x 3-foot Heat Shield Sleeve by Ethan Delaney

I bought this to protect the large wiring harness that powers my ECM on a 4WD project truck where the ECM is mounted under the hood on the driver's side fender and where the main wiring is The Wiring harness runs from the rear of the engine and then to the ECM. Limited mounting space or extra clearance, you are where you are. So the wiring harness is exposed to the heat of the driver's side (V8) exhaust manifold and I wanted to help reduce the effect of radiant heat. This is an option for that.
