Standard Ignition EGV679 EGR Valve

Standard Ignition EGV679 EGR Valve

Standard Ignition EGV679 is a mechanical exhaust gas recirculation valve built for direct-fit replacement on select GM applications. It uses stainless steel valve components, a polyester-reinforced silicone diaphragm, and a reinforced gasket to support reliable sealing and consistent operation in high-temperature exhaust environments.

Key Features

• Mechanical EGR valve with no electrical connector
• Stainless steel internal valve components for durability
• Polyester-reinforced silicone diaphragm resists thermal aging up to 200°C
• Reinforced gasket included for complete replacement
• Direct-fit design for straightforward installation
• 1 hose connector and 2 bolt holes

Detailed Description

The Standard Ignition EGV679 exhaust gas recirculation valve regulates exhaust flow back into the intake stream to support emissions control on older GM vehicles. It is a direct replacement for applications such as Chevrolet Camaro, Chevrolet Corvette, Pontiac Firebird, and related Buick, Cadillac, GMC, Oldsmobile, and Pontiac models listed in the fitment data. This part cross-references Eastern Catalytic 41133 for the same application. EGV679 also cross-references 2-3072C and 4F1026 for select applications.

Built as a mechanical EGR valve, EGV679 is suited for vehicles that use a no-connector configuration and a two-bolt mounting pattern. The included gasket helps complete the replacement at the mounting surface, while the reinforced diaphragm and stainless steel components are selected to handle repeated heat cycling in emission-control service.

What It Helps Address

• EGR valve sticking or restricted movement
• Exhaust gas recirculation flow faults
• Rough idle related to EGR malfunction
• Emissions test failures tied to EGR performance
• Vacuum-related EGR leakage at the valve body

Installation Notes and Tips

• Verify the vehicle’s emissions package before ordering; fitment includes California, Federal, and U.S. emissions-specific applications.
• Confirm the OE reference number and mounting style match the original valve.
• Inspect the mating surface and vacuum hose connection before installation.
• Use the included gasket during installation to help ensure a proper seal.
