Clean engine compartment, Jas.
I cut the passenger side inner fender well just above the battery so removal is quick and easy now. I like the looks of the KB cover but it does restrict air into the filter. I opened the end of the cover, machined some vents on the engine side of the cover, and installed plastic vents on the top and bottom of the cover. I cut an opening in the inner fender well for the bottom vents to fit in. The vents are angle so the direction of water from the tire will not be a direct path to the filter. I also installed a longer K&N filter.
My theory: Looks cool, gets plenty of air, fender well keeps water out of the engine compartment but can be removed quickly.
