The emission control system is a combination of parts that are incorporated into vehicles to reduce the amount of toxic emissions exhausted by the engine. Oxygen sensors, catalytic converters, throttle actuators, etc. - all these components work together to help regulate the engine performance and efficiency as well as limit the amount of partially burned or evaporated gases to go into the atmosphere. Even if at least one of them wears out or fails to function, the whole system won’t be able to ensure neither cleaner environment nor optimal vehicle’s performance. If you’ve noticed a decrease in fuel efficiency, reduced power or unstable idle, chances are one of the emission control system components is out of order and you should replace it immediately.

Dorman has you covered with a dazzling line of premium quality replacement emission control parts that allow you to restore reliable operation of your emission control system without spending big dollars. All components are made with the use of the finest materials and advanced manufacturing technologies to bring original equipment quality and reliability. Since at Dorman they use the same industry standard as Original Equipment Manufacturers, you can be sure their products fit, function and look exactly like the originals but cost less than the parts from the dealer. Boasting exceptional durability and wear resistance, the emission control parts designed by Dorman are guaranteed to provide hassle-free service for as long as possible.
