1000cc BMW 540i E39 M62 Fuel Injectors

1000cc BMW 540i E39 M62 Fuel Injectors

The stock fuel injectors on the BMW 540i E39 M62 are designed for factory power levels. However, when increasing horsepower through tuning, forced induction, or other modifications, stock injectors quickly become a bottleneck. Upgrading to 1000cc injectors ensures your engine gets the right amount of fuel, preventing lean conditions and maximizing performance.

Key Benefits

✔ Supports High-Performance Builds – Ideal for naturally aspirated and forced induction setups.
✔ Compatible with All Fuels – Thanks to stainless steel internals, these injectors handle pump gas, ethanol (E85), and race fuels.
✔ Precision Flow Rate – Rated at 1000cc/min at 3 bar pressure, ensuring consistent fuel delivery.
✔ Plug-and-Play Fitment – Designed with a USCAR injector plug style, these injectors fit seamlessly into the E39 M62 engine.
✔ Tuning Data Included – Comes with exact match tuning data, making ECU tuning easier and more accurate.
