EGR

Shop New OEM EGR (Exhaust Gas Recirculation) valves, tubes, and coolers for GM vehicles. Our factory-original emissions components are sourced from GM surplus — the same valve flow rate, port configuration, and cooler capacity as installed at the factory.

The EGR system reduces NOx emissions by recirculating a portion of exhaust gas into the intake manifold. A failed EGR valve causes rough idle, increased emissions, and P0400-series fault codes. OEM replacement valves provide the exact flow characteristics required by your engine's ECM calibration.

Clean the EGR passages and throttle body when replacing EGR components to restore full system function. Verify part numbers against your engine's RPO code before ordering.
