Spool IFX150 Direct-Injection Injectors – BMW B58 Gen 1
Spool IFX150 Direct-Injection Injectors – BMW B58 Gen 1
Spool IFX150 Direct-Injection Injectors – BMW B58 Gen 1 is a Spool Performance upgraded direct-injection injector set for high-output BMW applications while retaining factory-style direct-injection control.
- Upgraded high-flow direct-injection design
- Operating capability: up to 290 bar
- Tuning/calibration changes are required
- Designed to retain controlled idle and low-load behaviour appropriate to the application
Fitment: BMW B58 Gen 1 applications. Supplier copy contains conflicting percentage figures, so M Lab intentionally describes these as upgraded high-flow injectors without publishing a disputed exact gain.
Important: fuel-system capacity and calibration must be matched to the complete engine combination. M Lab can assist with BMW-specific installation and calibration planning.
Dispatch: Special order — allow 2–3 weeks.

Fuel-system selection and installation
Fuel-system parts must be selected around the complete combination of engine generation, fuel type, target output, existing pump and injector configuration, and the calibration strategy. A component appearing for an engine family does not mean it replaces every factory or upgraded fuel-system arrangement used on that engine.
Professional installation and calibration are recommended where the product changes fuel pressure, pump control, injector flow, ethanol-content input or port-injection operation. Confirm wiring, plumbing, electrical load, controller requirements and compatible supporting hardware before ordering.
Before ordering
Select your exact BMW through MLAB My Garage and review the product options, included parts and installation requirements. Where a vehicle has been modified from its original engine, transmission or fuel-system specification, contact MLAB with the VIN and current hardware list so the combination can be checked before supply.
MLAB support
MLAB by Boost and Tune can assist with product selection, workshop installation and dyno calibration for supported BMW applications in Melbourne. Product availability and lead time should be confirmed when ordering supplier-built or special-order components.
