It went in fast and my Beemer thanked me for opening up it's air passageways so it can breathe in our dusty, dirty, haboob laced, air here in the valley of the sun.

I found filter easy to fit and feel it has improved performance power of my bmw 320i family members have used k@n and do recommend buying one

Great product. It does improve performance on the car like it says it does. Installed on 2000 bmw 323i. Filter must be universal. It came with a gasket to line the upper part of the filter housing. Have to use that liner in addition to the filter to fit and work properly. K&N should not have used this liner and should have made made a direct fit. Hence, the 4 star. Saw the you tube on how to clean the filter. While drying time is needed, the car will be down. In order to keep the car running, I'll have to install the old type air filter. However I cannot install the old type air filter with that gasket in the way.
