Ordered, received, installed and tested on an '11 990R. Already tuned for motohooligan airbox with K&N, and the CPR breathes quite similar to the old setup. I am happy.
Best part was that it is more quiet compared to the K&N which has this very sharp bark between 4 and 5K. The CPR flattens this out and just breathes with a good base tune.
No bolts and nylock nuts included (as pointed out earlier). The fit could be more precise becaue if you lock one of the quarter turn tabs first, it's very hard to lock the second and vice versa. I think the whole issue is that it's difficult to get the filter enough over to the right side when the lip of the filter goes under that base on the left side. Maybe it will get more play after some more usage, but lets see.
I ordered a baseplate w/o breather hole bc that hose is now just venting to air in front of filter, ending in a filter sock zip tied to the frame.
