Product Details

The Bosch Workshop Air Filter line focuses on practical engine protection with a design that balances filtration and airflow. For the Honda HR-V, Bosch 5978WS uses a panel configuration and a dense pleated media structure to capture airborne contaminants before they reach the intake system. The polyurethane seal is engineered to support a consistent fit at the filter frame and help preserve sealing performance under temperature and moisture exposure. This part cross-references Honda 1722051BH00 for the same application.

Common Issues This Filter Can Address

• Dust and road debris entering the engine intake
• Restricted airflow caused by a loaded or dirty air filter
• Reduced filtration performance from worn filter media
• Seal leakage around an aged or hardened filter edge
• Routine maintenance replacement for Honda HR-V air filtration

Installation Notes and Tips

Verify the air box and filter dimensions against the vehicle before installation. Replace the filter during scheduled maintenance or sooner if the element is visibly dirty, damaged, or saturated with debris. Confirm the filter seats evenly in the housing so the polyurethane seal contacts the frame uniformly. Compatible with 2016-2022 Honda HR-V, workshop air filter application.
