Get all the fuel system parts you need to support over 400 horsepower on your 2003 and up SRT-4. The system starts out with the Walbro 255lph high pressure fuel pump that feeds your choice of 550cc, 650cc, and 750cc RC Engineering saturated injectors (high impedence). You'll need a way to manage that fuel so we include the Apexi Super AFCII with detailed installation and tuning instructions. In order for the AFC to read a clean RPM signal, you'll need the DIS Tach Driver from MSD, which is also included with wiring instructions. Save big by purchasing the kit.
