Description
If you’re running E85 or ethanol blends in your Gen 3 B58 or B48-equipped BMW, the Fuel-It! Bluetooth/CANflex Flex Fuel Kit is a must-have for precision fuel management and peak engine performance. BMW engines are highly sensitive to ethanol content, and this plug-and-play solution allows you to monitor your ethanol mix accurately—without any permanent modifications.
Simply remove the stock low-pressure fuel line in the engine bay and install this kit using OEM-style fittings. The integrated Bluetooth app (or CANflex system) provides real-time ethanol content readings directly from your mobile device. When needed, revert to stock in minutes by reinstalling the factory fuel line.
