TCM Turbo Inlet Pipe for BMW B46 and B48 Engines
Free Shipping within Continental USA
TCM, is proud to announce the release of the high-flow aluminum turbo inlet pipe for B46 and B48 engines.
Improving the turbo inlet pipe will provide increased turbo efficiency and responsiveness by allowing the turbo to pull in more air due to the larger diameter tubing. Along with making the turbo perform better, you'll get a noticeable increase in induction noises and turbo spool sounds.
The TCM turbo inlet replaces the weak, and failure prone, plastic factory inlet with a more robust aluminum one. CNC machined fittings are utilized to ensure proper fitment and guarantee installation as a direct replacement to the OEM inlet.
The Factory inlet being made of plastic absorbs a lot of sound, dulling your induction noise. The TCM inlet fixes all this, but using aluminum, which helps carry the sound better. It also removes any inefficiencies and obstructions found in the OEM inlet that BMW put in place to dull the induction noise.
The result is an inlet that delivers not only more air and allows the turbo to be more efficient but also provides the oft desired amplification to the turbo induction soundtrack.
Features:
- Increased turbo efficiency and reliability courtesy of maximum unimpeded and uniform airflow.
- Eliminates the factory sound resonator for increased turbo vocalization.
- 24% increase in overall volume over OEM inlet.
- Average of 13% larger internal diameter throughout (maximum cross-sectional area allowed).
- Direct replacement of OEM turbo inlet.
- Quick and easy bolt-on installation.
- Lifetime Warranty against defects
