MMR Alloy Boost Pipe Upgrade for Mini F5x Platform — F56 Hatch, F55 5‑Door, F54 Clubman — B38 B48 B37 B47 Engines

Eliminate weak plastic ducting and unlock smoother charge air flow with MMR’s aluminium boost pipework. This direct-fit hard pipe set replaces the brittle factory pressure tubes on F56, F55 and F54 models, giving cleaner airflow, sharper pedal response and dependable sealing on both standard cars and tuned setups. Ideal for B38 and B48 petrol plus B37 and B47 diesel variants.

We run this kit on our own Minis and our customers consistently report tighter boost control, more consistent performance and a smart OEM plus look under the bonnet. If you are chasing reliability and crisp response from the turbo system, this is the go-to intercooler piping upgrade.

Why this turbo pipework is a smart upgrade

• Replaces fragile OE plastic pressure pipes that are known to split and cause boost loss
• Alloy hard pipes maintain shape under load for stable boost and repeatable performance
• Smoother internal profile with constant-radius bends for improved charge air velocity
• Leak-free CNC connections with proper O‑ring sealing for peace of mind
• Crinkle black powder-coated finish with subtle laser etching for an OEM style appearance
• Direct swap for factory turbo outlet to intercooler and intercooler to throttle body pipework
