MMR Aluminium Boost Pipe Upgrade for BMW B58 engines

Give your B58-powered BMW the robust turbo pipework it deserves. The MMR aluminium boost pipes replace the fragile factory plastic tubing that often splits under increased pressure, delivering stronger construction, cleaner airflow and sharper throttle response. Finished in durable crinkle black with subtle MMR branding, this direct-fit kit looks OEM-plus under the bonnet while supporting remaps and spirited driving.

We run these on our own B58 builds and customer cars, and the feedback has been outstanding for fit, finish and reliability. If you are chasing a leak-free boost tract, improved spool and a smarter under-bonnet appearance, this is a proven upgrade that simply works.

Why this upgrade makes a difference

• Replaces the stock plastic turbo piping that can fail on tuned cars and high-mileage vehicles
• Mandrel-formed aluminium tubing with a smooth internal bore for reduced turbulence and better response
• Flow-optimised design helps minimise pressure drop compared with the factory parts
• Rigid construction resists deformation under load to keep boost control consistent
• Crinkle black finish for an OEM-style look with discreet MMR laser etching
• Precision CNC connections for a secure, leak-free seal on factory couplers
• Integrated 1/8 inch port for easy addition of water-meth or auxiliary sensors
• Direct-fit installation that uses the original mounting interfaces, no cutting required

What you receive

• Two aluminium boost pipes with CNC-machined ends
• High quality silicone coupler
• O-ring gasket
• C-clip
• Jubilee clips
• 4 x throttle body bolts
