Bosch 52lb (550cc) High-Impedance Fuel Injector

Bosch GT500 52lb/hour with EV6 / USCAR Connector – Drop-in fit for MK4/MK5 R32nn

nnGenuine Bosch High Impedance InjectorsnnThese injectors flow 52 lbs/hr at 43.5 PSI ( 3 BAR ) and more at higher PSI. In addition, these units are high-impedance. Despite the high flow rate, they are linear and controllable at low pulse widths and have been used in ULEV applications! This allows you to use a larger injector than normally possible without hurting idle and low speed driveability. Adding to the flexibility of application, these units are high-impedance; making them compatible with most ECUs, while delivering the most flow available in a High-Impedance injector. These injectors represent the most current Bosch engineering and are used on many high power oem applications including the GT500. Specifically this injector is best suited to a 4 valve configuration due to the wide split cone spray pattern. Many import tuners have raved about the quality of this injector in their 4V applicationsnnThese injectors are able to function at high fuel pressures and don’t exhibit the high fuel pressure handling problems found with many other high flow high-impedance injectors. Many tuners push these injectors to 6 bar and higher.nnEngine performance and running quality are enhanced through the optimized spray pattern. Unlike competitors “pencil stream” high flow injectors; these High Flow injectors utilize a multi-orifice tip for improved mixture preparation and atomization. This results in lower BSFC and better idle quality than many injectors with less flow.nnFeatures:nGenuine, reliable Bosch InjectorsnExcellent response characteristicsnRobust DesignnHigh ImpedancenLow Impedance performance characteristics with High Impedance CompatibilitynnSpecifications:nCoil Resistance: 12 Ohms (This high-impedance injector will work with all factory ECM/PCM injector drivers)nSpray Pattern: Wide Split Cone, (6 orifice)nElectrical Connector: USCAR (New-style V=EV6 / Oval / LS2)nFitted with Viton upper and lower o-rings.nStatic Flow Rate @ 43.5PSI (300kPa): 51.72 lb/hr = 6.52g/s = 544cc/min (+/-3%)nOverall Length: 65.5mmnDimensions: 48.5mm o-ring seat to seat, 53.5mm o-ring centerline to centerlinennApplications:nPerfect for 4 valve head applications looking for a high flow, wide dynamic range injector with superb idle qualitynnCross Reference:nBosch 0 280 158 117 (0280158117)nn nn
