Yes, that is the standard air inlet to the KLR air box.
Some owners "pull that rubber snorkel out".
Some owners drill four, 1 inch holes into the top of the air box, straight across, left to right.
Some owners drill six, 1 inch holes, which puts 2 holes directly above the filter. (which I personally don't like.)
Some owners 'carve-out' the entire top of the dirty side of the air box, called the "L" mod. (which I don't like.)
I personally like four, 1 inch holes, with the snorkel still in place.
I feel the filter stays cleaner longer, breathing cleaner air from under the seat, and less dusty air from the rear tire.
Modify at "YOUR OWN RISK"!
