BMW S58 Spool IFX350 Upgraded DI Injectors +30%

The Spool IFX350 upgraded DI injectors for the BMW S58 add 30% more flow while keeping the factory direct injection system in full control.

Why you need it

As power climbs, the stock S58 injectors become the limit. The IFX350 flows 30% more and delivers fuel consistently at up to 390 bar for better atomization and cleaner combustion. It keeps factory idle and low-load characteristics, so there is no need for a supplemental port injection system, and paired with the FX350 high pressure pump it supports very high power builds.
