Default Homemade Air Lid Seal

Have any of you tried to make a seal/gasket for you lid using RTV? The supplied K&N rubber seal they supplied for the lid is crap and keeps coming off.

I was thinking of putting a thick beed of some of the black RTV around the edge of the lid, then just letting it dry. Do you think it will hold?

I've also considered this. No reason why it wouldn't work, as long as you let it dry before driving again. The downside is that it would look like shiz with RTV everywhere...

I'd go to Home Depot and buy some black window insulation that's sticky on one side and use that.

I think I have some of what you're talking about. If its as flimsy as the provided rubber seal then it will probably tear off when putting the lid on also eventually.

Here's what I did (got the idea from another member on here):

Take the lid off
Clean underside of lid with denatured alcohol (anything will work, that's just what I had)
Leave air filter in place
Take wax paper, and place a sheet on top of the air filter so it covers the rubber seal (that doesn't seal worth ****)
Run a thick bead of RTV on the underside of the lid
Take lid, and put it back in place (so you'll now have a sandwich with the lid, RTV, wax paper, then filter), and lock the clips
Let sit overnight (or however long to let the RTV harden)
Take lid back off
Remove wax paper (it should be sticking to the RTV, but it shouldn't be hard to remove since it won't stick to the wax paper very well)

You now have a custom seal for your air lid.

...or just get some thin weather stripping.
