Valley Cover to Lower SC Manifold (Dirty Side):
'Clean' side(s):
Drivers:
Passangers:
Hooked into the intake:
If you don't have the Valley Cover to lower manifold like I do (the L99 does not have the outlet on the manifold), then the 'Drivers' side is considered the 'dirty' side and should go to the manifold, and the passenger's side goes to the intake. You would put the 'catch can' on the 'dirty side'...
The 'clean side' goes to the air intake (after the MAF)...
