Review on 🚘 Bosch Automotive 6031C HEPA Cabin Air Filter: Enhancing Air Quality for Audi, VW, and More by Danny Zapata

Revainrating 2 out of 5

Filter doesn't look dirty at all

It has a horrible chemical smell when you first install it, you wonder what treatment chemical you are inhaling. It takes some time to "weather". I don't joke about changing every 12,000 miles. At 9000 miles there is no airflow through the filter. The filter doesn't look dirty at all. I typically replace the OEM Mann canopy filter every spring, which for me equates to about 20,000 miles.

Pros
  • cool product
Cons
  • update available
