Step-by-Step Instructions

Follow these steps carefully

1

Open the front trunk

Open the front trunk on the 981 Cayman. The cabin filter is located under the cowl panel at the base of the windshield. The 981 shares this layout with the 991. Clear the frunk for working room.

2

Remove the cowl trim

Remove the plastic cowl trim at the windshield base. The 981 uses clips that release with gentle prying. Work from one side to the other. Set the trim aside safely.

3

Extract the old filter

Locate the filter housing under the cowl. Note the airflow direction indicators. Open the housing cover and slide out the old filter. Compare it to the new one for size.

4

Install the new filter

Clean leaves and debris from the empty housing. Insert the new filter in the correct orientation with airflow arrows pointing properly. Ensure it lies flat.

5

Reassemble the cowl

Close the housing cover securely. Refit the cowl trim, pressing each clip until it engages. Close the frunk lid.

6

Verify HVAC operation

Start the car and run the HVAC through all fan speeds. Verify strong airflow and no unusual noises. The new filter should eliminate any musty odors.

All Done!

Test your repair before closing everything up. If something doesn't work right, double-check your steps.

⚠️ Common Mistakes to Avoid

  • • Forcing the frunk trim clips - the 981 trim is delicate.
  • • Installing the filter upside down - check the orientation marks.
  • • Not fully seating the filter - it will cause a whistling noise.
  • • Using a cheap filter that does not seal properly.
