Sam, I think you're talking about the filters that fit in the original air box. I think the other guy is talking about the filters that require that you remove the air box and it is shaped like a cone.
: Not really much performance. Maybe 2-3hp at peak rpm if you're lucky, BUT it is washable, and guaranteed for ever :)
: That makes it worthwhile to me. (Considering my 750il requires two air filters!!).
: Get one. definitely recommended.
: have one on the taurus sho and mustang 5.0 and they sound a little throatier in the growl. Never noticed it in my 750il because its quiet as a mouse at any rpm range.
: : what do people think of the K & N air filter system? you know, the sporty-lookin one that replaces the BMW-installed air filter system. It promises a considerable change in performance, and that it is easy to clean and maintain. Thanks.
