Ramair PRORAM BMW 1/2/3/4 Series B48 Induction Kit (Carbon Lid)

Ramair PRORAM BMW 1/2/3/4 Series B48 Induction Kit – Carbon Lid (PRK-318-BK)

The Ramair PRORAM induction kit is a direct replacement for the restrictive factory airbox on BMW models fitted with the B48 2.0-litre turbocharged petrol engine. It is designed to allow more air to flow into the engine more freely, which can improve throttle response and give a more satisfying induction and turbo sound under acceleration.

This is a well-engineered kit that replaces several components at once – the standard airbox, filter, and inlet pipework – with higher-quality equivalents. The result is a cleaner, more direct air path to the turbocharger. For everyday driving, the improvement in throttle response is often the most noticeable change. On tuned or remapped vehicles, the benefits can be more pronounced as the engine is better able to breathe freely.

What Makes This Kit Different

The kit uses a 90mm inlet diameter pipe, which is larger than the standard setup and helps reduce restriction. Importantly, it retains the correct dimensions for the OEM MAF sensor – the MAF (Mass Air Flow) sensor tells the engine how much air is entering, so keeping this accurate is essential for the engine to run correctly. No modifications to the sensor or wiring are required.

The carbon fibre lid on the heat shield is a standout feature of this kit. Carbon fibre is lightweight and has natural heat-resistant properties, helping to keep the incoming air cooler and denser. Cooler, denser air contains more oxygen, which is beneficial for combustion and performance. It also gives the engine bay a purposeful, clean appearance.

• Black powder-coated aluminium heat shield with carbon fibre lid
