Most manuals say to swap the CAF out every 15-30K miles but it's often a PITA to access on many cars. Unless they live in a dusty environment or have strong allergies, most people neglect replacement for many, many years. I'm guilty of leaving them in for 75K but when they come out, they don't look that bad. How long do you guys usually go on a CAF? My Pilot's is a breeze to access so I'm going to pull it out for inspection. At only 25K miles, I don't expect it too be dirty.
