Title: what is this disc valve?
Post by: rojeho on August 31, 2011, 11:28:23 PM

Found this flopping around.  Does it fit into that tube just below?  What is the orientation supposed to be for the colors?  Light up or dark up?  For reference, that's the exhaust manifold to the left.  Between the exhause and the strut tower.

What is it?

Thats the check valve for the disa system on your intake. Think it goes black side down into the black air reservior just behind it in shot. Without it your disa system will not be working and top end performace will suffer
