Hi, Has anyone changed the air filter on their F15? Is it easy? I have bought a K & N filter but cant find any guidance on how to change filter on the newer model X5

Be inclined to return the k&N filter,
No performance gains will be merited, more likely, you will foul the Air mass flow meter and cause lumpy running. k&N filters are oiled and this is the cause of rough running, vapourised induction air picks up the oil and deposits in the intake system and sensors..

K&N fitted and an easy job and car running fine, the first stage done next the remap etc
