Great product. I purchased a 2012 x5d and was only getting 17.8 mpg - far below the stated 21 city. First tank of gas after I changed the air filter was 20.2. First thing I do with every new car is put a K&N filter in.

Very good product. Better than factory recommended.

Great replacement filter. Vehicle fuel economy seems to have improved by 6-7. Still early to tell. Even if there were not an improvement, I am very pleased with my vehicles running performance with the new air filter.
