Genuine Bosch EV14 Fuel Injectors these injectors represent the most current Bosch engineering and are used on many high power oem applications. Specifically this injector is best suited to a 4 valve configuration due to the wide split cone spray pattern. These 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. Engine 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.
