2nd filter I have owned. The 1st, mileage was a wash. Nice thing is that is reusable. Overall, it is a worthwhile investment.

The morning after installing the AFE filter I was driving and suddenly realized something was different about the performance of my car. I drive a 2000 BMW Z-3. The filter I replaced was clean so there was no decrease in performance due to clogging of air intake. My Z is more responsive on acceleration and pick-up during shifting. I have not yet checked for mpg increase but even if none, I will be happy with the increase in performance.

I had a K&N filter but I don't like the color (dark, looks not very clean). I replaced it with a green filter. I can hear the air flow hissing sound while driving. For me it's not a noise. Instead it sounds very smooth. I still have not got the chance to figure out if it improves horse power and/or gas mileage though.
