Delphi EG10304 Exhaust Gas Recirculation (EGR) Valve

OE-Style EGR Valve for Ford and Mazda Applications

The Delphi EG10304 exhaust gas recirculation (EGR) valve is built for vehicles that need precise exhaust flow control and stable emissions performance. It uses a stepper motor design, a square female connector, and a 6-terminal blade-pin layout for a direct-fit service replacement on select Ford, Mazda, and Mercury models.

Compatible with 2003-2022 Ford, Mazda, and Mercury applications, including Ford Fusion, Escape, Focus, and Transit Connect, this Delphi EGR valve is engineered from OE-based specifications for consistent fit and function. The EG10304 also includes a gasket and seal components for service-ready installation.

Key Features

• Stepper motor EGR valve design for controlled exhaust gas recirculation
• Positive backpressure configuration
• Square female connector with 6 male blade-pin terminals
• 2 mounting holes for OE-style attachment
• Exhaust port included
• Gasket or seal included for installation
• 2 vacuum ports with 17.0 mm diameter
• Delphi EG10304 part number for catalog and service reference

Detailed Description

Delphi EG10304 is an exhaust gas recirculation valve designed for emissions-system service on Ford Fusion, Ford Escape, Ford Focus, Ford Transit Connect, Mazda 3, Mazda 6, Mazda 5, Mazda CX-7, Mazda Tribute, Mercury Mariner, and Mercury Milan applications. Delphi builds this EGR valve using OE-based design specifications, material selection, and validation testing developed from more than a century of original-equipment experience. The result is a service part focused on accurate fitment, dependable electrical connection, and consistent exhaust flow control. If you are replacing a worn or sticking EGR valve on a Ford Fusion or Mazda 3, the EG10304 provides a direct replacement path for the original emissions component.

This part cross-references Standard Ignition EGV1025 for the same application.

What It Helps Address

• Rough idle caused by an EGR valve that is sticking open or closed
• Check engine light concerns related to EGR flow or valve position faults
• Emissions test failures tied to exhaust gas recirculation performance
• Driveability issues such as hesitation, surging, or unstable combustion at cruise
• Vacuum or sealing concerns at the EGR mounting interface

Installation Notes and Tips

Verify connector shape, terminal count, vacuum port layout, and mounting-hole pattern before installation. The Delphi EG10304 includes a gasket and seal components, but mounting hardware is not included. Clean the mating surfaces thoroughly and inspect the intake and exhaust passages for carbon buildup before installing the new valve. Confirm the vehicle’s calibration and emissions-system diagnosis before replacing the EGR valve on Ford, Mazda, or Mercury models.

Quality Assurance

Delphi uses OE heritage, controlled manufacturing processes, and validation testing to build emissions components that follow original-equipment specifications. The EG10304 is produced with OE-based material choices and thickness standards to help maintain consistent quality in service applications.
