Airtec Motorsport Big Boost Pipe Kit for BMW B58
Part of Airtec's expanding BMW range, this cold side boost pipe kit addresses a common weak point on the B58 — the factory pipes' thin plastic construction, which can split or fracture even at standard boost, and is more prone to failure once pressure is increased with a remap.
Airtec's direct replacement pipes are made from high-quality aluminium, able to withstand increased boost pressure, with a larger internal diameter for improved capacity and flow. The pipework includes a 1/8" NPT meth injection port and a CNC-machined flange retaining the original O-ring and spring clip at one end, with a machined flange bolting to the existing part at the other for a perfect fit. The kit includes a Pro Hoses silicone connector, jubilee clips and all fixtures.
