Bosch 550cc Injectors ATMSFO98 – MK2 Ford Focus ST & RS




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.
