GMC Heat Shields

Q: What is a heat shield? Why buy one?
A: Heat Shields are designed to protect your car from the harmful heat that is given off by the engine and exhaust system. Intense engine heat can damage plastic and rubber components, hurt the finish of the vehicle, and significantly decrease the engines performance. Motors are capable of producing more power when the intake charge is cooler, so if they suck in hot air from the engine bay, power will suffer. With performance heat shields you can keep the hot air away so that only cool air comes in, giving more horsepower and better efficiency. They will also reduce warping and cracking of components in the engine bay saving you on repair costs down the road. In addition aftermarket heat shields will provide a great custom look to any engine bay and help your ride to stand apart from the crowd.
