Every vehicle I purchase I order either a replacement drop in filter or an air intake kit. The drop in filters may be on the pricey side but the fact is in the long run you save money because you never need to buy another one just clean and reuse. I still have a recharge kit that I purchased many years ago again savings.I recommend you keep your paper filter for when I come time to clean and re-charge the filter.In my opinion to properly service the filter you will need a few days between cleaning,drying,re-oiling and letting the extra oil wick out before re-installation.I do the same thing for my air intakes buy a cheap knock off filter to use while recharging my K & N cone filter. Very satisfied with all my filters and intakes I have purchased over the years.

I have 2 cars and K&N filters are on both. I couldn't ask for a better filter. This one is for a 2012 fusion and my other one is on a 2000 Mustang GT. Both filters make the cars run so much better. Thank you K&N!

Having purchased my oil filters from this site previously, I found it a very easy to now start to purchase my air filters for my vehicle. It is a very easy way to find the exact filter for my vehicle. I will continue to use this site for all my future purchases.

Great product, they last for a long, long time. I used one filter on 3 different cars, same model for about 15 years with 25,000/yr. Clean and re-oil, no problem.
