Spool - Helix HPFP Overdrive Unit – BMW 135i / 335i E8x / E9x N54 / N55 Engine:N55 vooral bij getunede setupsThe Spool performance Helix HPFP Overdrive Unit has been developed for BMW N54 and early N55 engines to significantly increase the capacity of the original high pressure fuel pump (HPFP). By increasing the HPFPs rotational speed, the volume of fuel delivered is increased, thereby preventing pressure drops at higher power outputs. This provides an effective solution for high power builds without the complexity of additional port injection systems.
