After reading this forum and deciding to DIY my 05 Pilot EXL Navi cabin air filter, I purchased a Purolator filter and found these installation instructions inside. Thought I would share these instructions with the forum, particularly since they mentioned something important that I did not see noted: to disconnect the battery neg post and allow 3 minutes for the passenger air bag system backup capacitor to discharge, to make sure it does not get activated while replacing the cabin filter. Sure would be an expensive and possibly lethal job if it were activated in one's face.
