KKM Intake for your Mounty, less than 1/2 the price of that K&N system:

I use a KKM on my X, and a lot of others here also use KKM. I've had 0 problems with mine.
Just a couple of things to keep in mind:
1.) It's really not "just a tube". I know that K&N, at least, does flowbench testing, and dyno testing of their products to verify that they improve performance. Depending on the required bend(s),etc... what may seem like the best solution does not turn out to be the case (ie, it's not always the biggest pipe that performs the best.)
2.) The K&N FIPK, assuming you purchase one for your specific application, is 50 state emmissions legal. Most of the other brands are not, as they have not been submitted to the EPA for testing, or obtained a CARB E.O #. Granted, you may not care about this. It depends on how strict your local inspection nazi's are.
3.) If money is tight, and you're not worried about the emmissions legality, you might as well make your own. It probably won't be as good as an engineered commercial unit, like the K&N FIPK, but it will be close, and a lot cheaper. Buy a good quality cotton element cone filter, such as a universal K&N, and make the rest out of schedule 40 pvc. If you really want to be trick, and make it as nice as possible, use epoxy to smooth the inside transitions at the joints (elbows,etc..) You can also prob. get away with the using the rubber plumbing adapters, sold next to the pvc pipes (at least at home depot). I would use 2-1/2 - 3" pipe. Don't go any bigger; you'll kill the flow velocity, and really screw with the signal to the MAFS.
4.) No matter which route you take, plan on getting a custom tune ASAP. Any CAI tends to make these trucks run rich, w/o a tune to compensate. This is due to a change in airflow over the MAPS wire. I would recommend James @
