Overall Dimensions of a 250R K&N?

[offroadfury]

Hi guys. I have been looking at Aluminum Airboxes for my Z400. I noticed that the UM and Bare Performance say to use a 250R K&N air filter. I know that the 250R filter is bigger but was wondering exactly how much bigger it is. Thanks for the info.

c,mon.......I know someone out there has a 250R with a K&N filter on it. I just want to know how big around it is and the length.

hey this is matt bare from bare performance, the ID is 4 inches and I believe they are six inches long...

I think the main reason is not only cuz they are bigger but the air enters at a much higher velocity with the 250r filter. Ive heard my engine builder talking about this.
