"I installed a K&N filter on my 2006 BMW 330i and the increase in torque between 1500-4000 rpm was instantly apparent. I also removed the stock carbon filter which was only designed to help catch emission fumes. I trust that the k&n filter will keep my engine clean. The filter fit the OEM box perfectly. Overall I'm extremely happy with my purchase." —Adam A from Etna, WY bought a K&N Air Filters for a 2006 BMW 3-Series, 330i, 3.0L 6-cyl. engine.

Better for the planet also." —Henry T from Bumpass, VA bought an aFe Pro-Dry S Air Filters for a 2006 BMW 3-Series.
"K&N airfilter is awesome. I have one in all 5 of my vehicles that my family and I drive. I also recommend to all my friends. limited maintenance, more horsepower etc..." —Michael R from Mableton, GA bought a K&N Air Filters for a 2006 BMW 3-Series.
"The Pro Dry S filter for my BMW 325 is the only way to fly. Getting into the air box although not hard, is still time consuming. So an oil type filter is out of the picture.
The quality of the aFe filter is very good. It fits perfectly. Advertised performance gains seem missing.
The cost is high in comparison to the oil type aFe or K&N filters. I give this filter a 3 1/2 star rating because of the high cost." —Walter F from Fort Wayne, IN bought an aFe Pro-Dry S Air Filters for a 2006 BMW 3-Series, 325Xi, 3.0L 6-cyl. engine.
"Installed replacement filter in 2006 BMW 325i. Filter seemed to be good quality; heavy compared to paper filter. The housing took a bit of time to remove & re-install(I took about 45 min. but was being slow & careful. Reqires T25 Torx driver). No problems, running well after install." —Tom H from Modesto, CA bought a K&N Air Filters for a 2006 BMW 3-Series, 325i, 3.0L 6-cyl. engine.
"I've seen the ping-pong ball display demonstrating the difference between the K&N and other filters but wasn't convinced until I installed one in my car. It's as if I removed an obstruction in the car's breathing process. I was so impressed I installed one in my truck and one in each of my daughters cars. Thank you K&N." —Michael C from Medford, OR bought a K&N Air Filters for a 2006 BMW 3-Series.
