I ordered this to go on my Process West Track manifold for my 12 Subaru STI. The adapter is the same outside dimensions as the adapter that comes pre-installed on the throttle body but the inner diameter is larger to fit the larger hole in the manifold. The problem lies in the corners where the rubber gasket that sits in a machined groove comes slightly outside of the part where the manifold meets the adapter. I have checked with other people who have the same setup and theirs pokes out as well. I do not have my car together yet to confirm if there is a boost leak or not. Boomba said that they have sold many of these and apparently no one else has complained. I just thought it was worth mentioning that myself and others have this issue with the fitment.
