Keep clean, filtered air flowing to your engine with the Pronto Premium Guard Engine Air Filter PA99691. It drops in as a direct-fit replacement for the 2020-2024 BMW X3 and the 2020-2025 BMW X4, sitting in the air box between the intake opening and the throttle so the air reaching your engine is screened before it gets there.
An engine air filter traps dust, dirt, and airborne debris so grit doesn't reach the intake and internal engine components, helping restore proper airflow for normal engine operation as a clogged element is replaced.
- Direct-fit replacement: for the listed BMW X3 and X4 applications.
- Filters intake air: captures dust and debris carried in the incoming airstream.
- Routine service part: a restricted or dirty filter reduces airflow; replacing it is part of normal maintenance.
Signs the filter may need replacing include a visibly dirty or clogged element and reduced airflow at the air box. Replace on the interval in your vehicle's service schedule.
