Ramair Foam Intake Kit with Carbon Lid for BMW GXX B48

Ramair Foam Intake Kit with Carbon Lid for BMW GXX B48 (Pre-2022 Models)

This Ramair intake kit replaces the restrictive factory airbox on BMW G-series B48 engines with a high-flow foam filter, smooth intake pipe, and a carbon fibre lid – giving your engine better access to cool, clean air while adding a sharp look under the bonnet.

The standard airbox is engineered primarily for noise reduction and low production cost, not for maximum airflow. Ramair’s kit takes a more performance-focused approach, combining a dual-layer foam filter with a heat-shielded enclosure to reduce the warm, turbulent air that can blunt throttle response and limit mid-range performance.

Please note: this kit is designed for pre-2022 BMW GXX B48 models only. Always confirm compatibility before ordering.

What to Expect from This Upgrade

With the factory airbox removed and the Ramair kit fitted, the B48 engine can draw in air more freely. The result is a more immediate response when you press the accelerator, a stronger mid-range pull, and a cleaner induction sound from the turbo – noticeable without being intrusive. The carbon lid also gives the engine bay a purposeful, finished appearance.

This is a realistic, well-rounded upgrade for drivers who want improved intake efficiency and a more engaging drive from their B48-powered BMW, whether the car is on standard tune or already remapped. An ECU remap (software that adjusts how the engine control unit manages fuelling and timing) is not required, but a mapped vehicle may see additional gains thanks to the freer-flowing intake.

Kit Contents and Key Features

• Carbon fibre lid for a clean, premium under-bonnet finish
• Black formed heatshield to block hot engine bay air from entering the intake
• Ramair dual-layer performance foam filter – washable and reusable
• Smooth rotomoulded intake pipe to reduce air turbulence
• Complete fitting hardware including brackets, fixings, and installation instructions

The kit uses existing factory mounting points throughout, so fitting requires no cutting, drilling, or permanent modifications to the vehicle.

Fitment

This kit fits BMW G-series (GXX) models powered by the B48 2.0 petrol turbo engine, built before 2022. Use the vehicle lookup tool on this site or check the Vehicle Fitment tab to confirm compatibility with your specific model before ordering.

Installation and Maintenance

Fitting is straightforward for anyone comfortable using basic hand tools. The kit is fully bolt-on, aligns with factory mounting points, and comes with instructions to guide you through the process.

The foam filter is reusable – clean and re-oil it at regular service intervals, or more often if you drive in dusty conditions. Using the Ramair maintenance kit is recommended to keep the filter performing at its best and to extend its service life.
