Review on 🚗 Bosch 6025C HEPA Cabin Air Filter: Compatible with 02-09 Audi A4, A4 Quattro, RS4 by Sean Purnomo

. Firstly the airflow in the cabin filter is perfect, didn't notice a decrease like the others in this post, so if you have a 2007 Audi A4 2.0T these machines blow a lot of air. The filter seems a little less tight on the sides but right after a tight fit I put everything back together and turned on the car, cranked the AC and heaters up to blast, the smell was AMAZING! I've tried all the air purification features and haven't noticed any drop in air purification performance, smells cleaner and fresher only time will tell but for now the Bosch Cabin Hepa filter is my filter!
