Yep, just replaced mine for the first time (82k on the odometer) and they were absolutely caked. I called around to pretty much every Cleveland area Honda dealer and found them for 30.00 each (got quoted as high as 42.00 ) If 4th gen Preludes have them, I think they should be in the same spot (behind the glovebox). I don't know if they had this for 92-96 models. It's easy to check, though. Just drop the glove box and you should see a plastic clip right in plain view. Remove the clip, and if you see two white frames with the words "air flow" and a directional arrow printed on them, you have it.
