Thread: GTI-R O2 Housing Gasket size?

Hey guys,

Does anyone know the diameter of the 3-bolt gasket that goes between the O2 housing and downpipe on a GTI-R? I need a new one but i dont want to take the pipes apart more than once.

Please let me know when you can guys! Thanks!

I have always used a 3" copper gasket. this requires one or more holes to be enlarged so it mounts up.

2.75" just like the Subaru up pipe gasket.
