MAHLE GS34030 Fuel Injector O-Ring Kit

The MAHLE GS34030 is a professional-grade Fuel Injector O-Ring Kit designed to restore proper sealing at the fuel injector mounting points. MAHLE is a globally trusted OEM supplier, and this kit delivers the same precision fit and material quality found in original equipment assemblies.

Fuel injector O-rings are a common source of fuel leaks and rough idle conditions. Over time, heat cycling and exposure to modern fuel blends cause O-rings to harden, crack, or shrink—leading to vacuum leaks, fuel odor, and poor engine performance. Replacing them with MAHLE's engineered sealing components helps restore a reliable, leak-free connection between the injector and fuel rail or intake manifold.

Key Features:

• OEM-quality sealing materials formulated to withstand heat, fuel, and pressure
• Precision-molded O-rings for consistent, leak-free fitment
• Trusted by OEM manufacturers and professional technicians worldwide
• Restores factory sealing performance on worn or damaged injector seals
• Includes all necessary O-rings for a complete injector reseal

MAHLE is one of the world's leading suppliers of engine components and sealing systems, supplying major automotive OEMs across the globe. The GS34030 kit is an ideal solution for fuel injector service during tune-ups, injector cleaning, or injector replacement procedures.
