According to Perrin, it fits the 08+ WRX and 05-09 LGT. However... it relocates the BOV port to the rear about 1". So it's not an 'easy' fit. I probably could have got it to fit had I removed the intake manifold. Trying to fit it from underneath the intake just wasn't going to happen on the OB, maybe the LGT is better?
You also need to cut your PCV hose and jumper the connector. This is, however, is easy relative to the BOV problem.
