Standard Ignition EGV308 EGR Valve

Standard Ignition EGV308 is a mechanical exhaust gas recirculation (EGR) valve built for direct replacement on select Pontiac and Oldsmobile applications. It uses stainless steel valve components, a polyester-reinforced silicone diaphragm, and a reinforced gasket to support reliable sealing and consistent operation in emission control systems.

Key Features

• Mechanical EGR valve design
• Stainless steel valve components for durability
• Polyester-reinforced silicone diaphragm resists thermal aging up to 200°C
• Reinforced gasket included for complete replacement
• One hose connector
• Standard Ignition part number EGV308

Product Details

This EGR valve is used in emission control systems to regulate exhaust gas flow back into the intake stream under the correct operating conditions. Standard Ignition EGV308 is built with controlled manufacturing processes from component to finished part, helping maintain consistent fit and function. This part cross-references EGR101 and EGR1205 for the same application. It is a direct-fit option for vehicles such as the Pontiac Firebird, Pontiac Grand Prix, and Pontiac LeMans in listed OE configurations.

What It Helps Solve

• Rough idle caused by an EGR valve that is sticking open or closed
• Check engine light related to EGR flow or valve performance
• Emissions test failure tied to exhaust gas recirculation faults
• Driveability issues from improper exhaust gas recirculation control
• Vacuum leak concerns at the EGR valve mounting point

Installation Notes

Verify OE number and emissions calibration before ordering. Confirm the vehicle uses a mechanical EGR valve with one hose connector and the correct gasket style. Fitment includes 1973-1979 Pontiac Firebird, 1973-1976 Pontiac Bonneville, Catalina, Grand LeMans, Grand Prix, Laurentian, LeMans, and Parisienne, plus 1975 Oldsmobile 98 in listed applications. Review the OE notes for California or Federal emissions coverage where specified.

Quality Assurance

Standard Ignition manufactures emission components with quality control maintained throughout the production process, from individual parts to the finished valve. The stainless steel construction, reinforced diaphragm, and included gasket support dependable replacement performance in the intended applications.
