"I have purchased these filters for three different cars. They have clearly improved performance, more in my Saturn than in my Subarus and never have to be changed. I haven't tracked their impact on gas mileage. They do have to be cleaned, but very infrequently and it's really easy." —Richard K from Madison, CT bought a K&N Air Filters for a 2003 Subaru Outback.
