If you're running E85 or ethanol mixes in your RAM 1500, you need this kit!

Know your exact ethanol content in real-time via the CANFlex or JB4 app on your smartphone or tablet.

This complete flex fuel kit (FFK), also known as an ethanol sensor kit, E85 sensor, flex fuel sensor, ethanol content sensor, fuel composition sensor, or flex fuel composition sensor, installs in about 30 minutes.
