Ramair Foam Intake Kit for Mini Cooper S (F66) & BMW M135i (F70)

Ramair Foam Intake Kit for Mini Cooper S (F66) and BMW M135i (F70) – JSK-413-BK

This intake kit from Ramair is a direct replacement for the restrictive factory air intake fitted to the B48 2.0i engine found in the Mini Cooper S (F66) and BMW M135i (F70). By replacing the standard setup with a free-flowing foam filter, heat shield, and intake pipe, the kit is designed to improve airflow into the engine – which can result in sharper throttle response and a more engaging induction sound, particularly under acceleration when the turbo is working hard.

Ramair are a well-established UK brand with a long history of producing performance air filters and intake kits. Their foam filter technology is known for offering good filtration alongside improved airflow compared to standard paper-element filters.

What is included

• Ramair foam air filter
• Black powder-coated heat shield – helps keep hot engine bay air away from the intake
• Carbon fibre two-piece top cover
• Rotomoulded intake pipe – a rigid moulded pipe routed to optimise airflow
• Full fitting kit with step-by-step instructions

What it does and why it matters

The factory air intake on these engines is designed with packaging and cost in mind, which often means it is more restrictive than it needs to be. Replacing it with this Ramair kit allows the engine to breathe more freely. On turbocharged engines like the B48, improved airflow to the turbocharger can sharpen throttle response and enhance the induction note – that rush of air you hear as the turbo spools up.

The included heat shield is an important part of the kit. It helps shield the foam filter from warm air rising off the engine, keeping intake temperatures lower. Cooler, denser air is better for engine efficiency and performance. The carbon fibre top cover adds a clean, purposeful look to the engine bay.

It is worth setting realistic expectations here: an intake kit on a modern turbocharged engine is unlikely to produce dramatic power gains on its own. The real benefits are a more responsive feel, an improved induction sound, and a cleaner, more purposeful engine bay.

Maintenance

The Ramair foam filter can be cleaned and re-oiled rather than replaced, making it a cost-effective long-term upgrade. Ramair’s own filter maintenance kit (CK-003) is recommended for this and is available separately.

Important: This kit is designed specifically for the B48 2.0i engine fitted to the F66 Mini Cooper S and F70 BMW M135i. Please use the vehicle lookup tool on this site, or check the Vehicle Fitment tab, to confirm compatibility with your specific model before ordering.
