Product Reviews


  Excellent service. Great web site. The filter fit exactly as it should.
James Meyer Georgia
  The air filter was a perfect fit on my wife 2011 BMW 328i.
Ryan Wen California
  Thank you for a good high quality product that fits just as good as the original equipment. I have installed K&N air filters on all of my vehicles and I am very satisfied with the outcome. I have proven to myself that there is decreased fuel consumption by using K&N filters.

  Just plugged the air and oil filters in yesterday. I'm driving to Portland Maine tomorrow. I'll see if I get more pep. It worked on my last car ('08 bmw 328xi sport wagon) so it should work on the new one...

  I received my filter with a few days and it was a great fit. The only thing that wasn't so great about it has nothing to do with K&N and instead with BMW. It's a bit of labor to remove the filter box in order to replace the filter. I've always purchased K&N filters for my vehicles and have always been satisfied.

  I've been a K&N user for 30 years. I appreciate being able to order online direct from the company. I feel it assures me the best in customer service as well as possible (never needed it before) warranty. Why would I order from a third party (retailer) when I can go direct to the source?
This fit my BMW as it should and was as simple as always to install.
