ITG Profilter High-Flow Panel Air Filter for BMW M140i (2016+) F20 F21 F22 | Drop-In Performance Intake Filter | Washable Reusable Oiled Foam | B58 B58B30A 3.0 Turbo | OE Airbox Upgrade 1 Series

Upgrade the breathing of your BMW M140i with a high‑flow drop‑in panel air filter engineered for the B58B30A powerplant. This washable, reusable foam element replaces the restrictive factory paper insert inside the standard airbox, improving airflow while maintaining outstanding engine protection. Perfect for fast road use and track days, it’s a simple intake upgrade that delivers reliable results on the 3.0 turbo.

Why this performance air filter stands out

• Triple‑layer, oiled foam construction holds far more dirt than a paper element, keeping restriction exceptionally low even when loaded with contaminants.
• Consistent flow helps the turbo breathe more freely for crisp throttle response and smooth, sustained pull through the rev range.
• Extended service life in normal road use — lasts at least four times longer than a standard disposable filter, reducing waste and ongoing costs.
• Motorsport‑derived materials and build quality for dependable filtration and airflow on spirited drives and competition use.
• Subtle enhancement to induction sound for a more engaging driving experience without adding drone.

• Direct replacement panel filter for the stock airbox
