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.
