Oem EGR metal gasket
Used this on my 24 WRX to replace the metal OEM crush gasket on the upper part of the EGR pipe while doing a Perrin low profile intake return nozzle. Full disclosure, don't bother with the Perrin nozzle, it's way more of a hassle than it's worth. If you do, definitely replace both gaskets on the EGR pipe as reusing the old opens up the possibility of a leak. 4 lb of torque on this gasket by the way, that's like hand tight with three fingers on a little 10 mm wrench if you don't have a inch pound torque wrench. Don't overdo it
