MAHLE GS34032 Fuel Injector O-Ring Kit

The MAHLE GS34032 is a professional-grade fuel injector O-ring kit designed to restore proper seals on fuel injectors in a wide range of Asian and domestic vehicles. MAHLE is a globally recognized OE supplier, and this kit meets or exceeds original equipment specifications for a reliable, leak-free fuel system repair.

Fuel injector O-rings are critical components that prevent fuel leaks at the injector upper and lower seats. Over time, heat cycling and fuel exposure cause these seals to harden, crack, or shrink — leading to fuel odors, rough idle, misfires, and potentially dangerous fuel leaks. Replacing them with quality MAHLE seals restores injector sealing integrity and helps maintain proper fuel system performance.

Key Features:

• Manufactured to OE specifications by a Tier-1 original equipment supplier
• High-quality rubber compound engineered to resist fuel, heat, and chemical degradation
• Includes upper and lower O-rings to fully service the injector sealing points
• Direct-fit replacement — no modification required
• Suitable for professional shop or DIY installation

The MAHLE GS34032 kit is compatible with a broad range of Toyota, Lexus, Scion, Chevrolet, Pontiac, Mitsubishi, and other vehicles. Always confirm fitment with your vehicle's year, make, and model before installation.
