FUEL INJECTOR 15-pound-per-hour High Impedance Performance fuel injectors maintain precise control of fuel delivery and atomization for more power, better throttle response, and improved fuel economy. Every one is all-new – not remanufactured from a used core and not a modified stock injector. A new, low-mass disc design creates a spray pattern for ultra-fine atomization and ensures accurate metering control – even at ultra-low and ultra-high duty cycles. These high-impedance performance injectors operate at higher fuel pressures without any loss of metering control and are perfect for use with superchargers
