BMW 540i G30 / G31 B58 High-Flow Aluminium Cold Air Intake Kit

Product Overview

This high-flow aluminium cold air intake kit is designed for the BMW 540i in G30 sedan and G31 Touring form, powered by the B58 3.0-litre turbo inline-six. It replaces the factory intake ducting with aluminium pipework and a filter, giving the turbo an easier path for incoming air and making the smooth straight-six a little more vocal. It is a tasteful upgrade for 5 Series owners.
