Genuine Mazda KD45-61-J6X Cabin Air Filter – CX-5, Mazda6, Mazda3

Genuine Mazda KD45-61-J6X Cabin Air Filter

Keep your Mazda's cabin air clean with the genuine KD45-61-J6X cabin air filter (current Mazda part number KD45-61-J6X-9U). It captures pollen, road dust, and airborne particles before they reach the climate system, helping maintain steady airflow and a fresh interior.

A clogged cabin filter is a common cause of weak A/C airflow, slow defogging, and stale odors. Replacing it takes just a few minutes behind the glovebox — no tools required.
