Is it time to replace the injectors on your Duramax and want to prevent leaks and poor fuel delivery? The MAHLE Fuel Injector Seal Kit is designed to reseal your injectors and restore performance in 6.6L Duramax engines. When injector seals wear out or become damaged during removal, they can cause engine misfires, rough idling, hard starting, and significant power loss, reducing engine efficiency and creating drivability problems. This OE-quality seal kit provides the components needed to reseal one injector, helping maintain proper fuel system pressure and ensuring your injectors operate exactly as intended. Whether you're replacing injectors or performing preventative maintenance, the GS33505A helps deliver the leak-free fit and reliability diesel owners expect.
This MAHLE kit is designed to meet or exceed factory specifications. These precision-manufactured seals provide a tight, reliable fit that helps prevent leaks and maintain proper injector positioning. Each kit services one injector and is built to deliver the same level of sealing integrity trusted by OEM manufacturers and professional technicians.
