We are proud to bring out this truly awesome product that makes getting the required Flex Fuel hardware on your BMW and A9X Supra incredibly easy with minimal effort — all installable right in your own driveway.

Our kit is entirely plug-and-play with the factory vehicle harness. No cutting, splicing, or modifying OEM wiring or connectors is required. Installation takes only minutes and can be fully removed without leaving a trace on the vehicle.

Our team used SolidWorks to design a Flow Optimized Flex Fuel Sensor Adapter (FFSA) to ensure completely unobstructed fuel flow with no added pressure drop, even at full fuel pump capacity. This is especially important when maximizing the factory fuel system with ethanol blends and higher horsepower setups.

The flex fuel sensor housing is designed to integrate neatly into the factory BMW fuel hat location.

The Flex Fuel Sensor Adapter also includes two 1/8 NPT ports, allowing the installation of an auxiliary fuel pressure sensor for vehicles not equipped with a factory fuel pressure sensor. Depending on fitment, either port may be used.

Install the bootmod3 FlexFuel Plug-and-Play Kit, flash your flex fuel-enabled bootmod3 OTS MultiMap or Custom Map, and you’re ready to go — without ever worrying about ethanol or gasoline blend percentages again.

It doesn’t get easier than this.
