Ramair Pleated Intake Kit with Carbon Lid for BMW GXX B48

Ramair Pleated Intake Kit with Carbon Lid – BMW GXX B48 (Pre-2022)

The Ramair Pleated Intake Kit is a direct replacement for the factory airbox on BMW G-series B48 engines, built specifically for pre-2022 models. It replaces the restrictive standard setup with a freer-flowing intake system, helping your engine breathe more efficiently – and giving the engine bay a noticeably cleaner, more purposeful look.

What It Does and Why It Matters

BMW’s factory airbox is designed around noise reduction and manufacturing cost, not maximum airflow. As a result, it can limit how efficiently air reaches the turbo, particularly when you’re pushing the engine harder. The Ramair kit addresses this by replacing the stock setup with components designed to reduce restriction and improve air delivery.

In practical terms, you can expect sharper throttle response, stronger pull through the mid-range, and a more audible turbo note – without the intake becoming intrusive or overly loud. A formed heatshield is included to help reduce heat soak – where hot engine bay air gets drawn into the intake – which is a common issue in slow-moving traffic or at lower speeds.

What’s Included

• Black formed heatshield to help block hot engine bay air from the intake
• Ramair dual-layer pleated performance foam filter
• Carbon lid two-piece top cover for a clean, premium finish
• Smooth rotomoulded intake pipe to reduce turbulence in the airflow
• Full fitting kit including all required brackets and fixings

Performance and Tuning

This kit works well on both standard and already-tuned vehicles. You don’t need an ECU remap (a software adjustment to the engine’s management system) to benefit from the upgrade. However, if your car has already been remapped, the improved airflow may allow your tune to work more effectively – potentially unlocking a little more from your existing setup.

Installation and Maintenance

The kit uses existing factory mounting points and requires no cutting, drilling, or permanent modifications to your vehicle. Installation is bolt-on and should be straightforward for anyone with basic mechanical ability.

The pleated foam filter will need to be cleaned and re-oiled periodically to maintain performance – more frequently if you drive regularly in dusty conditions. Using a Ramair maintenance kit is recommended to keep the filter performing at its best and to avoid any potential issues with airflow restriction over time.

Fitment

This kit is designed for BMW G-series (GXX) models fitted with the B48 2.0-litre turbocharged petrol engine. Please note: this kit is compatible with pre-2022 models only. Use the vehicle lookup tool on this page, or check the Vehicle Fitment tab, to confirm compatibility with your specific model before ordering.
