Alloy Boost Pipe for BMW G Series B58

Replace the fragile factory plastic pipework on your B58-powered BMW G platform with a tough, high-flow alloy boost tube that looks smart and works even better. Built from quality aluminium and engineered for a factory-style connection, this upgrade delivers rock-solid reliability under increased boost pressure for remapped and stock cars alike, with a clean, OE-style appearance under the bonnet.

• Precision machined boss for the manifold pressure sensor to ensure perfect alignment
• Integrated methanol injection port for future-proof tuning or boost reference
• Machined ends for a secure, leak-free join with OE hardware
• Osprey textured wrinkle finish for a durable, heat-resistant coating
• Bespoke colour options available on the upper pipe section to suit your build
• Plug-and-play fitment that reuses original fixings and connections

Why this upgrade

The stock plastic boost plumbing is known to fatigue and split, especially on tuned setups. Our alloy hard pipe maintains consistent internal diameter, resists deformation at higher boost, and keeps your B58’s airflow stable for dependable performance. It is a straightforward swap that enhances durability, tidies the engine bay and supports future tuning with an integrated meth port and accurately machined sensor provision.

Finish choices

Choose the rugged Osprey wrinkle-textured coating for long-lasting protection against heat and corrosion, or ask us to colour-match the top pipe for a bespoke look. Ideal for detailed engine bays and show builds without compromising function.

Proven by us

We have fitted and run this boost pipe on our own cars and for customers. Feedback has been excellent, fitment is spot on and the coating stands up to real-world use. Exactly the kind of upgrade you want for a dependable B58.
