N55/S55 High Flow Injectors – S63 EU5 - Dorch Engineering

These are the OEM injectors for the BMW M5 (S63 Engine) and the highest flowing injectors of this family from Bosch. In terms of mechanical fitment, they will drop into any S55 and N55 engine that we currently support with our HPFP systems.  We typically have very limited stock, but they can be purchased at FCP Euro with a lifetime warranty!

NOTE: Please be aware that these injectors do require coding via ISTA, along with proper tuning before running them. Most tuners are quite familiar with these injectors as they’ve been successfully used in high-powered S55 builds for years.
