Product Overview

The EGR valve, OEM number 6421401060, is an electrically controlled valve that routes a measured amount of exhaust gas back into the engine's intake, reducing combustion temperature to lower emissions. It opens and closes constantly as the engine control unit adjusts exhaust gas flow to driving conditions, so its internal motor and valve seat wear and can carbon up over time, which makes it a regular replacement item in the emissions category.

A stuck, clogged, or failing EGR valve can cause rough idling, poor performance, and check engine warning lights, so a properly functioning replacement matters. GSK Auto manufactures this EGR valve to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm the OEM number match before shipping.

What Is an EGR Valve?

Function: The EGR (exhaust gas recirculation) valve redirects a controlled portion of exhaust gas back into the engine's intake system, lowering peak combustion temperatures and reducing the formation of nitrogen oxide emissions.

Working Principle: The engine control unit signals the EGR valve's internal electric motor to open by a precise amount based on engine load, speed, and temperature. This lets a measured volume of exhaust gas flow into the intake stream, where it dilutes the incoming air-fuel mixture and reduces peak cylinder temperature during combustion.

Importance: The EGR valve plays a direct role in meeting emissions standards and keeping the engine running cleanly. A valve that sticks open, closed, or responds incorrectly can affect engine performance, fuel economy, and emissions compliance.

Common Failures & Signs: Check engine light with an EGR-related trouble code. Rough or unstable idle. Hesitation or poor acceleration. Increased fuel consumption. Failed emissions test. Exhaust or burning smell from carbon buildup around the valve.
