True OEM replacement
Style: BE-151P 1-Pack
True OEM replacement for the cabin air filter of my 2016 Hyundai Sonata SE. It fit perfectly and was the same quality and size as the one previous installed. Installation took less than 2 minutes. Way better value than the ones the dealership or oil change want to sell you. I will definitely buy this again.
