It is a direct swap for the factory cabin filter, so you can replace the stock element without modifying the HVAC housing. Searching for a VF2074 cabin air filter for a 2020 Mazda CX-30 2.5L or a K&N Mazda 3 2.5L cabin filter should bring up this exact part number.
Before ordering, confirm that your vehicle falls within the listed application. Fitment ranges differ across the sources we checked, so verify the model year and trim against the manufacturer's application guide for VF2074. Check the filter's dimensions against your old element before installing. The filter sits behind the glove box on these models, which makes replacement a quick job for most owners who are comfortable removing a glove box panel.
Replacing this cabin filter is typically a glove-box-area job. Confirm the access steps and the airflow arrow orientation with the manufacturer's install documentation before you start, because the install sheet was not retrieved for this listing.
