BMW B58 G‑Series Charge Pipe Kit – Gtech Motorsports

Improve reliability and response on your BMW B58 G‑Series with the Gtech Motorsports alloy charge pipe kit. Replacing the weak factory plastic pipe, it uses mandrel‑bent 6061 aluminium, a 3"–2.5" taper and CNC‑machined connections to handle higher boost, improve airflow and support stock or tuned builds.

Key Features & Benefits:

• High-strength alloy: Mandrel-bent 6061 aluminium for durability.
• Direct OEM fitment: CNC-machined throttle body connection, no mods needed.
• Optimised flow: 3” to 2.5” transition for smooth airflow and faster response.
• Boost-safe: Beaded ends with heavy-duty clamps prevent blow-offs.
• Performance gains: Improved throttle response, reduced turbo lag.
• Methanol-ready: Built-in meth injection port supports advanced tuning.
• Durable finish: Hard anodised black coating for corrosion resistance.
