Have used K&N filters on a few cars. I think they are great. I haven't noticed any mileage change on ny 2013 Lincoln hybrid.

I have been a K&N user for a long time when I had my Mustang's. I had no reservations using one in my Fusion Hybrid. Perfect fit as always! Thanks for a great product!

After learning that the Ford Service Department where I had taken my car for 30K service didn't even have replacement filters for the hybrid, I decided to buy my first ever K&N filter. While I can't speak to longevity, we saw an improvement in gas mileage over our best-ever trip ratings. The fit on this item was excellent - the factory equipment filter had molding tabs left on the corners and had play in the gasket channel. This filter had very smooth molding and fit perfectly in the gasket ring. As the Atkinson cycle on our hybrids creates different flows of intake air than a traditional engine, I'd guess that gasket fit is pretty darn important.
