The ITG ProFilter WB-439 is a high-performance replacement panel air filter designed for Generation 3 MINI models F54, F55, F56, F57 (One, Cooper, Cooper D, Cooper S, Cooper SD and JCW).
Handmade in Britain, this filter uses ITG's multi-layer reticulated foam construction to provide an effective balance of airflow and filtration for everyday driving, track days and performance applications.
Designed to fit directly into the original airbox, the WB-439 replaces the standard disposable paper filter without requiring an aftermarket induction kit or modifications.
Unlike conventional paper filters, the ITG ProFilter is washable and reusable, making it a practical long-term alternative to regular filter replacement.
