GMC Sierra PCV & Breather Components

The GMC Sierra appeared on the market as a freestanding model at the same time as the Chevy Silverado, back in 1998. Both vehicles are technically identical, representing full-size pickups crafted to meet the needs of the U.S. drivers. While the Silverado is more practical and features simpler interior trim being consequently more affordable, the Sierra has always been more upscale and luxury. And two years after the official release of the Sierra, when there appeared a demand for a more upmarket version of the truck, the automaker introduced the C3 edition, which was later renamed the Denali.

Every modern vehicle comes equipped with a number of features which help it meet the emission control requirements and make it environmentally safe. One of important parts of the emission control system is a PCV valve which takes harmful vapors to the intake for them to get burnt in the combustion chamber, together with the air/fuel mixture. If this component is malfunctioning, it is a must to replace it the sooner the better so your vehicle can pass the emission test. And in our catalog of GMC Sierra PCV & breather components, you will find everything needed to restore your pickup truck.
