After changing the old filter (the same one) with this new one, I noticed a much greater air flow and much better smelling air. You can not beat the price for this filter. The lowest price of a filter for my 2011 Prius was $20.00 at a local auto parts store. For the price I change this filter once a year. I live in Florida and the A/C is always on. So it is comforting to have the best clean air possible.
I recommend this filter.
