Turner Motorsport Silicone Charge Pipe / Boost Pipe for BMW M340i B58 (G20/G21) - Turbo Outlet to Throttle Body Intercooler Pipe Upgrade - 4-Ply Reinforced with MAP & Temp Sensor Ports - Fits 3 Series M340i xDrive

Turbo boost pipe upgrade for BMW 3 Series M340i

Swap out the fragile factory plastic boost tube for a proven, high quality upgrade that delivers reliability and sharper response. This Turner Motorsport silicone boost pipe replaces the standard turbo outlet to throttle body pipe on the BMW 3 Series M340i with the B58 engine, giving you stronger construction and smoother flow for tuned or stock setups.

Why upgrade

The original plastic piping becomes brittle after repeated heat cycles which can lead to splits, cracks and boost leaks under load. This reinforced replacement is designed to handle elevated pressure without drama while improving airflow for a crisper pedal feel.

Key features

• 4-ply reinforced silicone main tube with a smooth internal bore for excellent flow
• CNC machined 6061-T6 aluminium throttle body flange and turbo coupler, hard anodised in black for durability and OEM appearance
• Direct fit with the factory turbo retaining clip for a secure, hassle-free install
• OEM-style provisions for MAP sensor and temperature sensor for plug-and-play compatibility
• Built to cope with increased boost on tuned cars while remaining a great reliability upgrade on standard vehicles

Real-world confidence

We have fitted this upgrade in our own workshop and customer feedback has been excellent. Drivers report improved throttle response, consistent boost and peace of mind under hard use.

Fitment

Designed for the BMW M340i with the B58 engine on the G20 platform.
