I looked but didn't find one for the HHR. Only for the Cobalt SS. Will that one fit? I only ask because there's another one that is apparently for the HHR SS but it looked different. For one of em on this site the small tube is at a angle

while the other one on this site
http://www.genuinesaab.com/catalog/p...id=827&osCsid=
the tube is straight. So which one is the correct one?

Sorry I haven't answered yet.
Here is the link: http://www.forgemotorsport.com/conte...roduct=FMDVVXR
My exact order from Forge Motorsports:
ProductID: FMDVVXR
Name: Recirculation valve for the Astra or Corsa VXR
QTY: 1
When ordering, they will ask if you want 90 degree or straight for vac connection. You want straight.
-------- First Impressions -------
After 120 miles so far, love the response and hold of boost.
With the stock bypass/BOV, I used to wonder if the power would be there, when accelerating at 3/4 or half pedal, and then pushing to the floor, sometimes the power was there, sometimes it would stay same (stuck).
Now it's accelerates every-time with Boost!!!! PSI shoots up and zooom everytime....not sometimes. Also find I am coasting more, rather than always having a foot-into-it! At speed so much faster, efficiently. Love it!
I also reset my fuel average to see if that gets back to over 30mpg like when my BOV/Bypass is replaced all the time.
------------------Another great feature ----------------------
I can replace the spring without removing the whole thing. Just unscrew the cap the vac connects to and swap springs.

Was tired of the sticking, overboost, etc. of the stock bypass valve.
Purchased an aftermarket replacement. Do I really need to point out which one is stock and which is aftermarket?
Took minutes to install. The spring pictured is an extra they send with, I left the one in as assembled...a tad stiffer.
Will report back after a week of driving. 80 miles daily and a 9 hour trip beeing done on Saturday.
