Standard Ignition EGV400 Exhaust Gas Recirculation (EGR) Valve

Standard Ignition EGV400 EGR Valve

The Standard Ignition EGV400 is a mechanical exhaust gas recirculation valve built for direct replacement on select Jeep applications. It uses stainless steel valve components and a polyester-reinforced silicone diaphragm to handle heat and maintain consistent operation in demanding emission-control service.

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

Detailed Description

Standard Ignition EGV400 is an emission control replacement part for Jeep Cherokee, CJ5, CJ7, J10, J20, and Wagoneer models across 1977-1984 applications. It is built as a mechanical EGR valve with a reinforced sealing design, making it a practical choice for restoring exhaust gas recirculation function on vehicles that rely on stable vacuum-actuated operation. This part cross-references Delphi TD4770W and Febi-Bilstein 30331 for the same application. The EGV400 part number is also referenced in multiple OE and aftermarket interchange listings for Jeep EGR service.

What It Helps Address

• Rough idle caused by improper exhaust gas recirculation flow
• Emission test failures related to EGR system malfunction
• Driveability issues from a sticking or worn mechanical valve
• Vacuum leakage at the EGR valve connection point
• Heat-related diaphragm deterioration in older emission systems

Installation Notes and Tips

Verify the vehicle’s OE number and match the valve configuration before installation. This EGR valve uses one hose connector and two bolt holes, and the included gasket should be used to help ensure a proper seal. Confirm the mounting surface is clean and free of carbon buildup before fitting the new valve on compatible Jeep Cherokee, CJ5, CJ7, J10, J20, or Wagoneer applications.

Quality Assurance

Standard Ignition states that it maintains quality control throughout the manufacturing process, from component selection to finished product. The EGV400 is built with stainless steel components and a heat-resistant reinforced diaphragm to support consistent emission-system service.
