Great filter, definitely an improvement over the oem BMW air filter (E36 320i coupe owner).

I wanted the cai system, however the drop In seems to be doing just as good at present. I look forward to purchasing more products from you in the near future. Let me know if you do lawn products also. That would be immense. Thanks much.

I've used K&N filters in all my cars over the years... they never disappoint. The filter comes pre-oiled which always an added bonus.
Jeff T, San Diego, California
Installed the filter but didn't notice any different in power or gas mileage. Just a replacement part but good thing is you can clean and reuse it.
