Mahle G33579 Exhaust Gas Recirculation (EGR) Valve Gasket

Product Overview

Mahle G33579 is an exhaust gas recirculation valve gasket for Subaru applications that require a steel sealing solution. It is listed for multiple Subaru models across recent model years, including Crosstrek, Forester, Impreza, Legacy, and Outback.

Use this gasket when servicing the EGR valve sealing interface on compatible Subaru vehicles. The part number G33579 is associated with direct-fit applications that call for a steel EGR valve gasket, including select Subaru Crosstrek and Subaru Impreza fitments.

Key Features

• Steel gasket construction for EGR sealing applications
• Application-specific fitment for Subaru emission control service
• Designed for EGR valve and EGR cooler-related sealing needs
• Mahle replacement part number G33579

Detailed Description

Mahle G33579 is an emission control gasket used in exhaust gas recirculation service. The fitment data shows coverage for 2017-2024 Subaru models, with notes identifying both EGR valve gasket and EGR cooler sealing applications depending on the vehicle. For Subaru Crosstrek, Subaru Forester, Subaru Impreza, Subaru Legacy, and Subaru Outback, this gasket supports the sealing point specified in the vehicle application data.

Because EGR systems operate under heat and exhaust exposure, the gasket material and application match are important for maintaining a proper seal during service. If you are replacing an EGR valve gasket on a compatible Subaru or servicing an EGR cooler connection on listed Subaru applications, G33579 provides the correct part reference for that job.

What It Helps Address

• Exhaust leaks at the EGR sealing surface
• Damaged or flattened gasket material during EGR service
• Improper sealing after EGR valve removal and reinstallation
• Leak concerns at listed EGR cooler connection points

Installation Notes and Tips

Confirm the vehicle year, model, and EGR service location against the fitment notes before installation. Clean the mating surfaces thoroughly and inspect the EGR valve or cooler flange for damage, carbon buildup, or warping before fitting the new gasket. Match the application notes carefully, since some Subaru listings specify the gasket for the EGR valve while others specify the EGR cooler connection.

Quality Assurance

Mahle is a recognized supplier in engine sealing and emission control components. Part number G33579 is cataloged for specific Subaru fitments to support accurate replacement selection.
