BMW M340i G20 / M240i G42 B58 3.0L Turbo 4 inch Aluminium Cold Air Intake Kit - Black and Red

Product Overview

This 4 inch cold air intake kit is designed for the BMW M340i (G20) and M240i (G42) running the B58 3.0L turbocharged straight-six. It replaces the factory intake path with a larger-diameter aluminium tract and an open-element filter, giving the engine bay a purposeful look while supporting a freer flow of air to the turbocharger inlet. The black and red finish suits owners who want a clean, motorsport-inspired appearance under the bonnet.

• Aluminium construction for a rigid, heat-resistant tract
• Black and red colour scheme that stands out in the engine bay
• Designed specifically around the B58 3.0L engine layout

Installation and Usage

Installation involves removing the factory airbox and intake ducting, then fitting the new tract, couplers and filter in their place. Check that all clamps are tight, sensors are reconnected and nothing contacts hot or moving components. Modern turbocharged BMWs are sensitive to air metering changes, so professional installation by a workshop familiar with the B58 platform is recommended. Inspect and clean the filter at regular service intervals.
