Fuel Injection Throttle Body Gasket

The Mahle G31578 fuel injection throttle body mounting gasket is an OEM-standard sealing part for restoring a proper seal at the throttle body interface. It uses paper gasket material and is built for direct replacement service on select Mazda and Kia applications.

Key Features

  • OEM-standard grade for factory-style sealing performance

  • Made for fuel injection throttle body mounting applications
  • Mahle sealing products are trusted by OEMs and technicians
  • Part number G31578 for easy identification

Detailed Description

Mahle G31578 is a fuel injection throttle body mounting gasket used to seal the throttle body to the intake side of the engine. A worn or damaged gasket can allow unmetered air leaks and unstable idle conditions, so replacing it with the correct gasket helps restore proper sealing. This part is a practical choice for Mazda Miata, Mazda Protege, Mazda MX-3, and Kia Sephia applications listed in the fitment data. The G31578 gasket is also referenced by cross numbers such as FEL-PRO 60984 and Beck/Arnley 039-5059 for the same application.

What It Is Used For

  • Air leaks at the throttle body mounting surface
  • Idle instability caused by a poor seal
  • Vacuum-related drivability complaints
  • Replacement of a damaged or compressed gasket
  • Service work on the intake and fuel injection sealing area

Installation Notes and Tips

Clean both mating surfaces before installation and remove all old gasket material. Verify the throttle body and intake surfaces are flat and free of debris before tightening. Confirm fitment by year, make, and model before ordering, since this gasket is application-specific.

Quality Assurance

Mahle states that its gaskets provide sealing products trusted by OEMs and technicians worldwide. The G31578 is listed as OEM Standard grade for consistent replacement service.
