"Easy E85 Flex Fuel Kit Installation: Maximize Savings and Performance"

A flex fuel kit allows your car to run on a variety of fuel mixtures, typically a blend of gasoline and ethanol-based fuels like E85. The kit includes sensors and software that detect the ethanol content in the fuel and adjust the engine's fuel injection and ignition timing accordingly. This means you can switch between different fuel types without needing to modify your car's engine control unit (ECU) or trigger a check engine light.
