Profilter high-flow panel element for BMW E46 diesel M47 and M47N engines

Give your turbo-diesel the clean, consistent breathing it deserves with the ITG Profilter drop-in panel element. This serviceable, washable foam insert slides straight into the factory airbox on E46 318d, 320d, 320cd and 320td models from 1998 to 2007, delivering superb dust control with exceptional airflow. Ideal for owners seeking an induction upgrade that supports smooth spool, strong mid-range and dependable protection without changing the stock box or requiring a remap.

What makes it a smart upgrade

• Triple-layer foam with oil treatment for outstanding particulate capture and engine safety
• High flow and low restriction to help your diesel breathe freely even as mileage builds
• Reusable and serviceable - clean and re-oil instead of replacing disposable paper elements
• Long life in normal road use - lasts significantly longer than a standard filter to reduce waste
• Motorsport-developed construction for consistency and durability
• Direct drop-in fit for the OEM airbox - no cutting, drilling or additional parts required
• Suited to daily driving, fast road and remapped M47 builds that need reliable intake performance
