The initial replacement of the cabin air filter on the 2nd generation Honda Odyssey (1999-2004) minivan is a P.I.T.A. Not only do you have to completely remove the glovebox and assorted trim pieces, you have to cut out a plastic crossmember brace behind it with a Sawzall! The metal brace in front of the plastic crossmember is re-installed with 8mm bolts & phillips head screws so no additional cutting is required on subsequent CAF replacements. This is discussed at 3 minutes into the attached video.
