OEM Fuel Filter Assembly replacement,  New Fuel Filter Included

The Upper portion contains the Fuel Temp Sensor inside of it, This sensor can go bad and create your Roxor to run in a "derated" state of power. We have found the derate to happen about 30 seconds after the vehicle has been started and will happen every time the key is cycled. When the ECM doesn't know the fuel temp, it will assume it's overheating and cut power as a safety measure. You can either replace this part to fix the issue or send us your ECM and we can revise your tune and add a $75 switch to create our own fuel temp sensor for the ECM to read from, but our recommendation is to replace the filter head.
