Baldwin Filters PA5666 air filter

The Baldwin Filters PA5666 is a rectangular cabin air filter designed for automotive climate-control systems. It measures 11 1/32 in length by 6 5/16 in width by 1 25/32 in height. The filter arrives new and ready for installation.

Upgrade from a clogged or missing cabin filter

Replacing a dirty element restores airflow through the heater and air-conditioning ducts. The jump is worth it when the old filter has reached its service interval or when reduced vent output and musty odours appear.

Check the housing dimensions and vehicle fitment

Verify that the filter housing accepts a rectangular element of the stated length, width and height. Confirm the part number matches the vehicle manufacturer's specification before ordering.

Questions about this item

Will the PA5666 fit a housing that measures 11 1/32 by 6 5/16 by 1 25/32 inches?

Yes, the filter's overall dimensions are exactly 11 1/32 inches long, 6 5/16 inches wide and 1 25/32 inches high, so it matches that housing size.

What is the correct orientation when installing this rectangular cabin air filter?

Install it with the airflow arrow on the frame pointing toward the blower motor; inserting it backwards is the common mistake that reduces filtration.

How often should the PA5666 cabin air filter be replaced?

Replace it at the vehicle manufacturer's recommended interval, typically once per year, or more frequently when driving in high-dust or high-pollen areas.
