Description AIRTEC Bosch 550cc Injectors ATMSFO98 – MK2 Ford Focus ST & RS 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. Many tuners push these injectors to 6bar and higher. Engine performance and running quality are enhanced through the optimized spray pattern. Unlike competitors’ single hole 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.   Features Genuine, reliable Bosch injectors Excellent response characteristics Robust Design High Impedance Low Impedance performance characteristics with High Impedance Compatibility RS Owners looking for 350bhp to 385bhp     View all AIRTEC products
