Standard Ignition EGV508 EGR Valve

Standard Ignition EGV508 EGR Valve

The Standard Ignition EGV508 is a mechanical exhaust gas recirculation valve built for direct-fit replacement on select 1994-1995 Chevrolet S10 and GMC Sonoma applications with California emissions. It uses stainless steel valve components and a polyester-reinforced silicone diaphragm to handle heat and wear in demanding emission control service.

Key Features

• Mechanical EGR valve design for emission control service
• Stainless steel internal valve components for added durability
• Polyester-reinforced silicone diaphragm resists thermal aging up to 200°C
• Reinforced gasket included for complete replacement
• Direct-fit replacement for easier installation
• One hose connector and two bolt holes

Detailed Description

Standard Ignition EGV508 is an exhaust gas recirculation valve engineered for vehicles that require a mechanical EGR design. It is built with stainless steel valve components and a reinforced silicone diaphragm to support consistent operation under high-temperature conditions. The included gasket helps restore the sealing surface during replacement, and the direct-fit design supports a straightforward swap on the correct application. This part cross-references EGR1041 and EGR1088 for the same application.

Fits 1994-1995 Chevrolet S10, N/A. Fits 1994-1995 GMC Sonoma, N/A. If you are searching for a 1994-1995 Chevrolet S10 EGR valve or a 1994-1995 GMC Sonoma EGR valve for California emissions, EGV508 matches the listed application.

What It Helps Fix

• Rough idle related to EGR flow issues
• Emission control faults tied to a sticking valve
• Driveability problems caused by improper exhaust gas recirculation
• Vacuum or sealing concerns at the EGR mounting point
• Check engine light conditions associated with EGR system failure

Installation Notes

Verify California emissions fitment before ordering. Confirm the valve uses a mechanical EGR setup, one hose connection, and a two-bolt mounting pattern. Inspect the mating surface and replace any damaged vacuum or exhaust passages during service. The reinforced gasket is included, but the mounting area should still be cleaned before installation to help ensure a proper seal.

Quality Assurance

Standard Ignition builds this EGR valve with stainless steel components and a heat-resistant reinforced diaphragm to support long-term emission system service. The EGV508 is a direct replacement part for the listed Chevrolet S10 and GMC Sonoma applications.
