Standard Ignition EGV390 Exhaust Gas Recirculation (EGR) Valve

Standard Ignition EGR Valve EGV390

Standard Ignition EGV390 is a mechanical exhaust gas recirculation valve built for direct emission-system service on select Chevrolet and GMC trucks and vans. It is a fitment-based replacement for California-emissions applications, including Chevrolet G30, P30, R30, V30 and GMC G3500, P3500, R3500, and V3500 models.

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
• 1 hose connector and 2 bolt holes
• Standard Ignition EGV390 for emission control service

Detailed Description

This exhaust gas recirculation valve helps restore proper EGR function on older Chevrolet and GMC applications that use a mechanical valve layout. Standard Ignition builds the EGV390 with stainless steel valve components and a reinforced silicone diaphragm to handle heat exposure in demanding underhood conditions. The included gasket supports a cleaner seal during replacement, and the part cross-references 17084724 for the same application.

Compatible With 1988 Chevrolet G30, 1988 Chevrolet P30, 1984 Chevrolet P30, 1988 Chevrolet R30, 1988 Chevrolet V30, 1984-1988 GMC G3500, 1988 GMC P3500, 1984 GMC P3500, 1988 GMC R3500, 1988 GMC V3500, and additional California-emissions Chevrolet and GMC truck and van applications listed in the fitment data. Standard Ignition EGV390 is a practical replacement when servicing emission control systems on Chevrolet G30 and GMC P3500 platforms.

What It Helps Fix

• EGR flow problems that can trigger drivability concerns
• Rough idle related to a sticking exhaust gas recirculation valve
• Emission-test failures tied to faulty EGR operation
• Vacuum-related EGR response issues on mechanical systems
• Heat-related diaphragm wear in older emission components

Installation Notes and Tips

Verify the vehicle’s emissions configuration before ordering, since many listed applications are California-emissions specific. Confirm the 2-bolt mounting pattern, single hose connection, and OE reference before installation. Clean the mounting surface thoroughly and inspect the gasket sealing area to help prevent exhaust leaks after replacement.

Quality Assurance

Standard Ignition states that it maintains quality control throughout the manufacturing process, from component selection to finished product. The EGV390 is built with durable materials and includes a reinforced gasket to support a complete EGR valve replacement.
