I loved the GFB on my WRX, and I actually experienced improved on/off throttle transition - it was a LOT smoother with the GFB than the stocker.

Now...do I do it again

 

The install was pretty easy, however 2 questions

1. my radiator hose is basically sitting right on top of the DV. Everything seems to work okay, just seems like it may be a problem.

2. anyone shorten up the vacuum line for better response?

leonard, you could relocate the valve closer to the i/c piping and farther away from the intake tube like I have, I initially did this due to how large the forge diverter valve is then I just left the configuration the same when I installed my MR valve.

 

How did you do this ? the lower pipe w/ the baffel does not seem to have a lot of movement.

 

Any ETA on the trumpet attachments?

 

will this work with Injen intake/piping system????????????

 

I hear the GFB bov has problems with MOST aftermarket intakes.
