Fuel-It! Hi-Flow CANflex Flex Fuel Kit - BMW S58 (M2/M3/M4/X3M/X4M)

OVERVIEW

The Fuel-It! Hi-Flow CANflex Flex Fuel Kit lets your S58-powered BMW M2, M3, M4, X3M, or X4M safely run E85 and any ethanol blend by monitoring real-time ethanol content and feeding it to your tune. Built around a genuine Continental ethanol content sensor with a high-flow stainless braided PTFE fuel line and plug-and-play wiring, it streams your fuel's ethanol percentage to the free Fuel-It!/BMS smartphone app over Bluetooth — unlocking the bigger power and cooler charge temps of flex fuel. The custom fitting includes a 1/8" NPT port for optional port-injection fuel pressure reference. Installs in about 30 minutes.
