This felt seal sits inside the door frame, completing the door’s weatherseal system and preserving the vehicle’s original interior fit and finish.

The felt-finish seal serves as a cushion and barrier between the inner door panel and the body shell, helping to block wind, water, dust, and road noise from entering the passenger compartment. It also maintains the original tactile and aesthetic quality of the vehicle’s door assembly.

Over the years, the felt on the inner door seal can flatten, detach, or degrade due to heat, humidity, and repeated door use. When this happens:
• Water and moisture may enter the cabin.
•  Wind noise at highway speeds can increase.
•  The interior refinment and original look deteriorate.
Replacing the seal with an OE Match quality part restores proper sealing, helps protect interior components, and keeps your classic Porsche performing and feeling as it should.

Replace the inner door felt seal if you notice any of the following:
•  Visible wear, fraying, or detachment of the felt surface
•  Water ingress or damp carpet near the door area
•  Excessive wind noise or whistling while driving
•  Loose or compressed seal that no longer provides firm contact
•  During interior restoration or door panel re-installation work
