How would you install this? I think I know how to install it...but I wanna know what you guys think.
kenny.
thanks in advance.

 

From a good ol Saab... I actually ganked one from the junk yard several weeks ago to sell on ebay.

Save your pennies and buy a metal one.

 

run it to the valve cover breather hose. Install a T connection inline. This will vent air back into the intake after the AFM but before the turbo.
(if this is a bypass valve similar to a BOV) The problem would be finding the correct size T adaptor.
