MMR B58 3.0T Silicone Turbo Inlet Intake Pipe/Hose for BMW M140i M240i 340i 440i F-Series (F20 F21 F22 F30 F32) - Gloss Black Induction Tube, Airbox to Turbo Bellows Delete - Direct Fit Performance Upgrade

Gloss black silicone air intake tube for BMW B58 - a direct swap for the factory corrugated pipe that runs from the airbox to the turbocharger on M140i, M240i, 340i and 440i F Series. Smoother internal walls reduce turbulence, the turbo breathes more freely and you get a crisper induction note when you get on the throttle. It also tidies the engine bay with an OEM Plus look.

We have installed this on our own cars and many customer vehicles. Feedback is consistently positive - cleaner airflow, a more responsive feel and a great soundtrack under load.

Key reasons to upgrade

• For B58 3.0 turbo petrol engines in BMW M140i, M240i, 340i, 440i F Series
• Smooth-bore design and larger internal radius for improved turbo feed
• More pronounced induction sound without any drone
• Deep gloss black finish for a subtle OEM Plus aesthetic
• Reinforced high quality silicone resists heat and deformation
• Stepped ends maintain a constant bore with tight, leak-free transitions
• Quick DIY install with basic hand tools - a simple bellows delete

Airflow focused upgrade

This replacement intake pipe removes the restrictive stock bellows section ahead of the compressor inlet, reducing pressure drop and smoothing the path into the turbo. It works perfectly with the standard airbox and panel filter and pairs brilliantly with high-flow filters, open cone intakes and uprated turbo elbows. If you have upgraded the intake system, this hose helps you realise the full benefit by minimising pre-turbo turbulence.

Built to last

Constructed from reinforced silicone in critical areas to hold shape under heat and load, while allowing the compliance needed for normal engine movement. Fit it once and enjoy reliable performance.
