About
EGR Valve

Cut down on emissions while boosting your engine's performance with a new EGR valve from AutoZone. Buy replacement parts that meet or exceed OE from trustworthy brands like Delphi, Dorman, and Duralast on AutoZone.com, and get free next day delivery or pick up your parts in one of our auto parts stores near you today.

The exhaust gas recirculation (EGR) valve is one of the earliest forms of emission control for internal combustion engines, but it does more than just help you ride cleaner. By helping the engine run at lower temperatures, it increases engine efficiency, providing a larger throttle position and reducing pumping loss.

Our valves are built to match OE fit and form for easy installation while exceeding OE lifespan for reliable performance. Get reliable parts for your make and model—we make it easy. Just enter your vehicle's year, make, model, and engine up above, and we'll show you parts that fit perfectly.

Signs of a bad EGR valve include rough idle, engine knocking, and a loss of fuel economy and power, but the symptoms vary depending on whether the valve is stuck open or stuck closed. Both mean trouble for your engine's combustion chambers, and both can cause a check engine light. A stuck open valve creates a vacuum leak which causes inefficient combustion. A valve that is stuck closed causes increased nitrogen oxide (NOx) emissions which disrupt engine timing which can make the engine knock. Checking what's wrong with the valve is easy. Just look under the hood of your car while it is running. If the engine is idling with the brake on, the valve should be closed. When the engine is revved, it should open. If the EGR valve is behaving unexpectedly, turn to AutoZone. We have everything you need to fix your valve and prevent more serious damage to your engine down the road.

EGR's full name, exhaust gas recirculation, gives a pretty good idea of what the valve does. Your engine's EGR valve is removes some exhaust gas so the inert gas can be recirculated and sent back to the engine cylinders, where it mixes with the air-fuel mixture before combustion. EGR systems were built to reduce NOx—a major source of smog in cities.

NOx forms in much greater quantities when nitrogen and oxygen mixtures are exposed to high temperatures. The inert gases sent back to the cylinders have already been through combustion, which makes them act as an absorbent for heat generated by spark ignition. This reduces cylinder temperatures and keeps the engine running cooler, effectively reducing the amount of NOx that can form in the vehicle's exhaust gases.

Get high performance and low emissions from your engine with a new EGR valve. AutoZone.com gets parts to you fast with free next day delivery or same day in-store pickup.
