You would be wise to go back to the stock air cleaner box. It won't take much time or effort once you obtain a stock box. Just make sure you get the correct box and tube for your model year. Looks like you have a 2005, so you will need to get the 05-06 box with the sensor on the back of the tube. You'll also need to get one of these if the K&N setup doesn't fit:

You'll probably need to remove a few clamps on the K&N setup, plus a couple bolts that hold it to the right side fender. Stock box will be replaced in a similar manner, with a few bolts on the fender and a clamp on either side of the tube.
