Spool Performance IFX800 Upgraded Turbocharger | Gen 1 B58
Spool Performance Upgraded Turbocharger for Gen 1 B58 Models
The stock turbo on the Gen 1 B58 has notable limitations, with a restrictive housing and small compressor that hinder efficiency and power potential. To resolve this, we developed an upgraded turbo featuring a larger turbine housing, compressor housing, and back housing, allowing it to operate efficiently at higher boost levels while maintaining reliability and safety.
This turbocharger retains all factory functions, driveability, and a stock-like appearance, making it the perfect balance between OEM reliability and aftermarket performance.
Fits the following Gen 1 B58 models:
M140i, M240i, 340i, 440i, 540i, 740i, X3 M40i
Please email us your VIN to customer_service@spoolperformance.us to confirm fitment.
