Too Difficult to Install for Me
I'm sure it's a good filter but installing it correctly is a pain for a CRF300L. It comes in two pieces - a frame and the filter. The filter just drops into the frame but doesn't fasten to it. I guess so one filter can fit into different vehicles with a different frame. Anyhow I couldn't get the frame to fit into the keeper recesses of the airbox while keeping the filter in the frame. Maybe could be done easily w/practice but I lost patience w/it.

Does not seal
The framework flexes too much and it will not stay in place. It pops out of place. Clips do not stay secure. If this happened after I put it together I could have destroyed my engine.

Missing mounting plate
This doesn't fit a Honda 300L. Did not come with mounting plate. As of right now it's useless
