I pulled the air ducts off of my F4 last night. the factory seals fell apart in my hands. What are people using to replace these? Anything special or just getting the factory seals?

I'm not looking at them at the moment, but would any of the window/draft stopper foam/rubber tapes work?

I smeared a very thin layer of silicone around the duct. Should do the same thing, it's removable, and didnt cost anything. Those factory seals suck. That they dont seal is one thing. That they disintegrated and are now located in my airbox is something else altogether.

I'll note you observations when I re-assemble.

Most MV dealers simply toss the seals when they fall apart and will reinstall the air ducts without them.

While I would recommend using new seals or some alternative, the ducts fit pretty securely without the seal from what I can tell.
