Product Details

Common Problems This Injector Can Address

- Rough idle from uneven fuel delivery
- Lean running conditions tied to restricted injector flow
- Fuel spray irregularities affecting throttle response
- Service replacement needs on aging MPFI fuel systems
Installation Notes and Tips
Replace injector seals during service, since the seals are single-use and Bosch notes they should not be reused after injector removal. Verify the vehicle application by year and model before installation, especially on 1983 Volkswagen Quantum applications noted from 01/1983. Confirm the injector type matches the vehicle’s MPFI fuel system and inspect the fuel rail, connectors, and sealing surfaces before reassembly.
Quality Assurance
Bosch supplies fuel-system components for service and replacement applications, and this injector is cataloged for direct-fit use on the listed BMW, Porsche, Audi, and Volkswagen models. Part number 62278 is supported by published interchange and fitment data for application matching.
