I have used K&N filters for years. I use them on my 911 and on my BMW E61 535D. You made me wait for the new air filter for the BMW F11 535d , but worth the wait. Easy to clean and re oil as I live near the beach and plenty of blowing sand. I have only one problem, the insurance companies (perhaps you should leave the name off) they do not need much of an excuse not to pay out.

This filter makes a noticeable difference to the car's engine response (BMW 640d M Sport) - I previously fitted a K&N replacement to a 635d M Sport, 320d M Sport , an X1 2.0d x-drive & a Ford Fiesta 1.25 : same effect - seems to produce a smoother engine response. Easy to fit (this particular unit isn't 'exactly' the same as the OEM Filter - it has a hard casing & forms an integral part of the top of the filter housing, but the K&N unit fits easily & is well sealed / 'weather proof. They are easy to clean also - with the correct products - from K&N (a bit messy, but easy) Great delivery service from K&N. As you can gather, I'm a convert.... I'll change any car filter to K&N if / when they have it available for my car model (had to wait a few years for the 640d) Excellent product.
