ACCEL 19-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. The special EV1 design is compatible with gas, E85 or methanol, and each one is all-new – not a modified stock injector and not remanufactured from a used core. 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 injectors operate at higher fuel pressures without any loss of metering control and are perfect for use with superchargers, where more fuel pressure and precise metering are an absolute must. Modern manufacturing processes reduce flow deviation between injectors, and both low- and high-impedance designs are available to match your vehicles ECU. These ready-to-install injectors come complete with fine-mesh fuel strainers and precision-molded O-rings.
