hahahaha, like grounding your exhaust? my real opinion is that if it goes in the airpath,then it blocks it. if you just do a cold air intake, exhaust, and get a chip so your computer enhances these changes, your as good as your gonna get without other mods. Oh, back to the thread topic, im sure you can use other models of a cold air intake, and do a custom thing on your own. all you need to know is that the filter needs to go to an area that is away from the engine, and you should build a shield around that area so it helps keep out the engine temp air.
parts needed:
2.5"-3" tubing
some sort of adapter for the conical air filter
air filter
you dont have to rely on the k&n part numbers, just go in the store knowing that you have a 3" tube, so pick the air filter that clamps to a 3" tube.
There are many options of tubing, remember you want lightweight. I did one that had my intake down by the radiator, but it was too heavy. Also look at some mustang kits, they might get you the parts you need, then you have to fab up the brackets.
here is mine, all i did was get an adapter, redrill the holes to fit, and attach an air filter. i know yours is a bit different but the concept is the same.
hope this helped at all,
