Ramair Foam Intake Kit for Mini Cooper S (F66) and BMW M135i (F70) – Carbon Fibre Lid (JSK-421-BK)
This intake kit from Ramair is a direct replacement for the restrictive factory air intake fitted to the B48 2.0-litre turbocharged engine found in the Mini Cooper S (F66) and BMW M135i (F70). It is designed to increase the volume and speed of air reaching the engine, which can sharpen throttle response and give the turbo a more noticeable induction sound.
Ramair are a well-established UK manufacturer of performance air filters and intake systems. Their foam filter technology is widely used across both road and motorsport applications, and this kit reflects that experience – using quality components throughout with a finish that looks the part under the bonnet.
What Is Included
- Ramair foam performance air filter
- Black powder-coated heat shield (CNC cut for precise fitment)
- Two-piece carbon fibre top cover
- Rotomoulded intake pipe
- Full fitting hardware and step-by-step instructions
Why Upgrade the Air Intake?
The standard factory intake is designed with cost and noise reduction in mind, which means it often restricts airflow more than necessary. Replacing it with a less restrictive system – like this Ramair kit – allows the engine to breathe more freely. On a turbocharged engine like the B48, better airflow can mean a more responsive throttle and, in some cases, small power gains when combined with an appropriate ECU remap (a remap reprogrammes the engine’s management system to take advantage of the improved airflow).
The carbon fibre lid also acts as a heat shield alongside the powder-coated panel, helping to keep the intake drawing cooler, denser air away from the engine bay heat. Cooler air is more oxygen-rich, which is better for combustion.
Filter Maintenance
Ramair foam filters are reusable and can be cleaned rather than replaced. Ramair’s own Filter Maintenance Kit (CK-003) is recommended for cleaning and re-oiling the filter to keep it performing correctly over time.
Important: This kit is designed to fit the Mini Cooper S (F66) and BMW M135i (F70) equipped with the B48 2.0i turbocharged engine. Please use the vehicle lookup tool on this page or check the Vehicle Fitment tab to confirm this kit is correct for your specific model and build before ordering.
