Product Details

Bosch Workshop Air Filter 5971WS is part of Bosch’s Workshop Air Filter line, a service-focused filter range for routine engine intake maintenance. The filter media uses a high-velocity cellulose construction with a pleated layout to increase filtration area, while the polyurethane seal is formed to help preserve fit and sealing integrity under underhood conditions. For drivers searching for a 2018-2020 Chevrolet Equinox engine air filter or a 2018-2020 GMC Terrain workshop air filter, this part provides a direct replacement option for the listed vehicles. This part cross-references GM 23279657 for the same application.

What It Helps Address

• Restricted airflow caused by a dirty or loaded engine air filter
• Dust and road debris entering the intake tract
• Reduced filtration performance from worn filter media
• Seal leakage around an aging panel filter
• Routine air filter service on Chevrolet Equinox and GMC Terrain models

Installation Notes and Tips

Verify the existing filter shape and housing before installation. Inspect the air box for debris, clean the housing sealing surface, and confirm the filter seats evenly all the way around. Replace the filter during scheduled maintenance or sooner if the vehicle operates in dusty conditions.

Quality Assurance

Bosch designs this Workshop Air Filter with pleated cellulose media and a polyurethane seal to support filtration efficiency and stable sealing performance in normal engine bay conditions.
