How often: every 42,000 mi or 4 yrs, whichever comes first. Turbo engines lose power and economy, and the airflow sensor gets dirty, when the filter blocks.

Bulkhead uses every second service; check your Maintenance Check Sheet for your exact vehicle.

Work safely: support the vehicle on axle stands, never a jack alone; let it cool first. Check figures against your workshop manual. You do this work at your own risk.
