MMR High-Flow Aluminium Charge Pipe Kit (Boost Pipes) for Mini John Cooper Works (JCW) F56/F55/F54 F5x B48 Turbo Direct Replacement Upgrade with Meth Bung Crinkle Black

Unlock stronger boost, faster spool and rock-solid reliability on your Gen 3 Mini JCW with this MMR aluminium intercooler pipework set. The factory plastic turbo plumbing on the F56, F55 and F54 John Cooper Works is notorious for splitting under higher pressure. Swap the brittle moulded pieces for robust metal hard lines and enjoy crisp throttle response, consistent pressure and confidence on the road or track.

Built to handle tuned B48 power

This bolt-on boost pipe upgrade is engineered for the BMW Mini 2.0 TwinPower turbo B48 engine found in JCW models on the F5x platform. Computer-modelled flow paths and smooth internal bores minimise turbulence and pressure drop, while the rigid aluminium construction resists deformation under load. Expect sharper response, better boost holding and fewer headaches compared with the OE plastic pipework.

Why enthusiasts choose this kit

• Direct fit metal boost tubing for F5x JCW with B48 2.0T
• Smoother airflow via precision bent aluminium hard pipes and high quality silicone joiners
