... but I believe he is stating that he does not have the AFM due to the generation of his engine.

snk33y, if you do not have the AFM, and you go with the HKS unit, you should be fine. You are only losing the by-pass feature which adds a bit of responsitivity and slightly better gas mileage. I wouls trongly urge avoiding the aftermarket valves that have a spring design (Almost all of them except the HKS).

Another option you have, is you can also vent your BPV to atmoshpere.
Just make sure to put a FILTER on it since it will allow air into your system. Look at the engine bay photos on my site to see what I mean.
Doing it this way you get all of the benefits of the OEM valve and the "noise".
