ITG Profilter - 1 Series (F20/21/22) M135i. M235i 12- N55B30A

ITG Performance Panel Filter for BMW F2x M Performance Models

Unlock sharper response and reliable airflow with ITG’s race-bred panel filter for the BMW F2x platform. Built around ITG’s triple-layer foam technology, this drop-in intake element delivers strong breathing performance while capturing fine dust and debris to safeguard your 3.0 turbo straight six. We run these on our own cars, and our customers consistently report crisper throttle response and a more purposeful induction note.

Why choose this upgrade

• High flow panel filter that supports smooth intake airflow for the N55 engine without compromising protection.
• Triple-layer foam matrix with oil impregnation traps contaminants effectively while keeping restriction low.
• Maintains low pressure drop even as the element loads with dirt, helping the engine breathe freely for longer.
• Extended service life. In typical road use it lasts up to four times longer than a standard paper element, reducing waste and saving money over time.
• Developed using know-how proven at the top of global motorsport, then refined for everyday performance cars.
