I put this in a 2005 CBR600RR. Compared to the stock filter, it looks like it would flow more air. Doesn't have a flame screen. Opening that holds filter material is actually smaller than the stock filter. Frame is made of a flexible rubber. Does not actually fit in the filter tracks, but once tightened down it will seal. Requires the use of new hardware (stock screws will not reach) and does not include them. I would not recommend this filter to anyone because of the fitment and hardware issue. Spend the extra money for a BMC or K&N. Because of the poor quality and attention to detail, I am rethinking my use of Bikemaster oil filters. This is disappointing.
