High flow air filter
It is a K & N filter that fits in the existing airbox. It is what is recommended on the Dinan website. I know there are a lot of people on the forum that seriously hate K & N products for BMW's, but if it is good enough for Dinan, it's good enough for me. I have thought about putting an AFE cold air intake, but I haven't made up my mind yet.

The high flow air filter - is this a cold air intake for the X3? I had a carbon fiber tube with high flow filter on my Z3. Expensive but nice. Or is it a filter that goes into the existing housing?
