The stock WRX and STi TMICs I've tried have had their gaskets kinda baked onto the surface of the TMIC itself, no issues.

But I got a bigger top mount yesterday, sans gasket. Think I might be leaking a wee bit, and it's just one of those best practice things to do anyhoo.

These are readily available online, but if anyone has one laying around, have cash/beer/sparkling conversation on hand.

LMK...

Bump : grimmspeed does the tmic gaskets now too, FYI. Sorry cant help ya locally.

@oaklandish - Good to know! I've a bunch of GS gaskets I'm gonna put on when I do my turbo swap. More is more so can't go wrong with a thicker gasket I guess.

 

You can get gasket maker sheet from AutoZone and make it yourself.
