Accel Performance Fuel Injectors Featuring a high-impedance design to function properly with the specified vehicle's ECUs, Accel's Performance Fuel injectors are all-new units, not remanufactured from used cores. They utilize a precision-ground Bosch-style pintle design, which produces a wide-angle conical sprat pattern of 150 micron diameter droplets, providing an ultra-fine fuel atomization and maximum emulsification for improved burn efficiency. This pintle design also produces a more accurate and consistently more repeatable fuel flow control than either the ball valve seat/deflector plate or disk injector designs. Accel Performance Fuel Injectors are 100% flow tested, balanced and marched to within +/- 1.5% of their normal pound/flow rating. Accel Performance fuel injectors also feature an anti-plugging vapor cap that virtually eliminates carbon build-up. Accel's low-mass internal needle valve and high-pressure spring assembly ensure faster response time and greater dramatic response range. These injectors also feature their noted flow rating permanently laser etched into the Accel-yellow molded top for the unmatched combination of great looks and instant recognition. They come complete and ready for installation with precision-molded O-rings and fine mesh fuel strainers.Brand: Accel Product Line: Accel Fuel Injectors ACC 150832 Injector Advertised Flow Rate (lbs/hr): 32 Injector Advertised Flow Rate (cc/min): 336 Quantity: Sold as a set of 4./ Injector Impedance: 14.4 ohms/ Driver Type: 12V saturated circuit/ Overall Height (in): 2.880/ Seat to Seat Height (in): 2.270/ Manifold O-Ring Outside Diameter (in): 0.573/ Fuel Rail O-Ring Outside Diameter (in): 0.574/ Outside Diameter (in): 0.943/ Injector Plug Style: Bosch/Amp Style/ Wiring Harness Included: No/ O-Rings Included: Yes/ Fuel Injectors, 32 lbs./hr., 14.4 Ohms Impedance, 12 V Saturated Circuit Driver, Universal, Set of 4 Picture generic.
