for BMW B58 — Pure 800 Turbo Builds
BW-B5815-800
Purpose-Built for Pure 800 Turbo Upgrades • High-Power B58 Builds • Maximum Airflow
Overview
The MST Performance BW-B5815-800 is a purpose-built induction upgrade engineered specifically for B58 G-chassis vehicles running the Pure 800 turbocharger upgrade. The kit combines a high-flow cold air intake with a turbo inlet sized to match the increased airflow demands of the Pure 800 unit, eliminating restrictions that limit a stock intake on a high-horsepower B58 build.
If you have invested in a Pure 800 turbo, your factory intake path is now the bottleneck. The BW-B5815-800 is the dedicated solution: a complete bolt-on system designed around the Pure 800's flow characteristics. Sized correctly, mapped to flow with the upgraded turbo, and built to MST's high standards of fit and finish.
