Suggested optional accessories:

Injectors:  Our kits use standard EV14 42mm injectors.  You can order them with the kit or supply your own injectors but you will need to add injectors for the kit to function.  Injectors are available in 550cc, 750cc, and 950cc flow ratings.

Port Injection Controller:  You must use a controller to run the additional injectors.  If you are running a JB4, then you will select the BMS port injection controller.  If you are not running a JB4 and just running a flash or factory ECU, you will need to stand alone (flash only) controller.

Flex Fuel:  If you are running ethanol mixes or E85, we highly recommend you run our flex fuel kit to integrate with the JB4 and to read your actual ethanol content.  The content can vary greatly from station to station and fill up to fill up.  If you already have one of our flex fuel kits installed, you can order the port injection kit and select "I already have your flex fuel kit" to receive the correct line from the ethanol sensor to the Tee fitting.  The supplied lines with your original flex fuel kit will work but the line from the ethanol sensor to the HPFP is bit long once you add the Tee fitting.
