Customer Reviews:
  • Solid product from a solid company.
    The filter installed with no problems, and was a solid fit. While I do not feel you receive huge gains from just the air filter, especially considering how well the stock filter flows, I do believe the K&N filter flows better. It is a great reusable, cleanable filter that will pay for itself overtime if you maintain it. As well as having great airflow. Can't beat the price either when considering any of the other after market drop in filters for the 335i. Some more technical reviews posted on e90post.com as well. ...more info
