If you're talking about a USDM Forrester, yes. If you're talking about a REAL FSTi, then I have no clue.

make sure it is throttle by wire... the bolt patterns for cable-driven and tbw manifolds are VERY different...


(ask marco how i know :lol:)

ask him about the time i helped him swap out his td04 and such for the vf39 and USDM STi manifold...

tools were flight-tested... believe me. good times.

You do realize we are talking about exhaust manifold, correct? I just realized you were talking about the intake manifold.

From everything I've read the exhaust manifolds on all the WRX/STi/Forester/LegacyGT USDM/JDM are all the same. Same diameter, same length, everything (except the twin turbo and twin scroll models).

You sir are wrong! FYI, the manifolds have different curves and different unconstant ID and OD throughout. Even the USDM '04 and '05 STi manifolds are slightly different.
