Not sure if this is what your are looking for, direct replacement for the stock bov, some of the pipe diameters will need be changed. Bosh part No 280 142 110 as used on the SAAB 1996 Turbo. I got mine from a SAAB dealer, SAAB part No 44418 about $40 . Apparently there are more reliable and are a third of the price of a stock Toyota bov, but as I said you will need to modify some of the pipe diameters. I haven’t noticed any difference in sound.
