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.
