K&N 57S-2001 Performance Air System for BMW 2.0 N20 Turbo

Let your 2.0-litre turbo breathe. The K&N 57S-2001 is a vehicle-specific airflow upgrade that replaces the restrictive factory air path on N20-powered BMWs across the F-series range. Expect crisper throttle response, stronger mid-range pull and a deeper, sportier intake sound that brings the turbo to life while maintaining excellent filtration.

This bolt-on air system is designed for enthusiasts who want an easy fit, reusable filter media and a noticeable improvement in driving feel without compromises. It is ideal for daily-driven cars and lightly tuned builds seeking a freer-breathing setup and that addictive induction soundtrack.

What makes it a great upgrade

• Engineered for BMW models with the N20 2.0 turbo petrol engine across F-series chassis codes.
• High-flow K&N filter media for excellent airflow with outstanding filtration.
• Washable and reusable element for long-term value.
• Direct-fit installation using basic hand tools with no cutting required.
• Fuller, more engaging intake sound under load.

We use K&N air systems on our own cars and have installed this part for many customers. Feedback on fitment quality, driving response and sound has been consistently excellent.
