APS Top mount intercooler y pipe gaskets - for reference confirmed same as stock STi
 

Just so it's out there for other peoples' reference. For APS TMIC for Newage (at least) the gaskets between the y-pipe and intercooler are the same as the stock Newage STi pieces, Subaru PN: 21896AA010

I took a punt that they were and ordered them anyway, and job's a good'en. :thumb: These units are probably becoming rare now as APS went under about 6 years ago apparently!
