The 2007 I drive is a PZEV. It has both a tube from the valve cover, crankcase ventilation, and a tube that is an EGR supply, exhaust gas recirculation. Both tubes connect to the rubber connector that is upstream
from the throttle blade. That is one of the pieces that the CAI replaces. Just phoned FSWERKS. They said that both tubes connect to the new CAI tube. I want to do this mod and am trying to learn to avoid problems. When I raced dirt tracks we used the outerware filter cover. They help keep the filter dry from occasional splashes, but the big thing is protection from flying debris. NO, I don't sell any of this stuff.
