Dan,
The cheap one's are pretty easy to put on. They should come with two holes in them for the plastic breather tube and the IAT connector. Pull those two things off the old air filter parts and then take anything to do with the OEM filter off the car. The new filter and connector tube will fit right onto the throttle body with the blue or red rubber connector and two hose clamps. The two things that you pulled off the old filter will now fit right into the holes in the new connecting tube. You can just see the IAT connector that plugged into my chrome tube right before it enters the throttle body.
