In the event that you dont want to spend $250 for 5 hp (I don't), this is an easy way to increase air flow into your engine and put a little more growl under your hood.
Step 1 (Picture 1) - Loosen the intake hose clamp (Red Arrow) and remove the two air box lid clamps (Green Arrows)
Step 2 (Picture 2) - Remove the air box lid and unclip the AFM wire clip. Set the lid aside. Remove air filter, and notice the dirt located at the base of the filter (Red Circle) because the "snorkel" has restricted air flow (reducing power). Remove the top screw (Green Arrow) and loosen the interior screw (Green Arrow) -- it will stay connected to the box. Do not worry about removing the screw you cannot access, it does not need to be removed.
Step 3 (Picture 3) - Remove the bottom of the air box by pulling up on the box with a firm, constant force. The remaining inaccessable screw by the washer reservoir (Red Arrow) will stay attached to the engine bay, and the box will come out with the lower rubber grommett still attached (Red Circle). Remove the zip-tie clip holding on the 1/2" rubber hose to the air box base.
Step 4 (Picture 4) - Mark the plastic to be removed with a pencil (Yellow Line), and remove the "snorkel" from the air box base. The easiest way to do this is to pry up the plastic around the lower clip (Red Arrow) and then pry up the plastic behind the upper clip (Green Arrow). DO NOT PRY TOO HARD, THE PASTIC WILL BREAK. You cannot deform the "snorkel" to get it out, you must gently and slightly deform the plastic around the clips. This will allow the "snorkel" to be easily removed.
Step 5 (Picture 5) - Use a hacksaw to cut the extra material off the "snorkel". Give yourself about 1/4" - 1/2" breathing room from the pencil line, in case you dont make a good cut. One straight cut at 30-45 degrees will work fine.
