It will only work with a Ramair if you cut the bottom of the scoop out to match the shape of the Ramair bottom and slide the Ramair in through the bottom of this scoop. It sits a little higher off the throttle bodies (stock velocity stacks are taller than the Ramair), so the bottom 1/8" of the Ramair will stick out the bottom of this scoop. You could add some rubber foam to seal the bottom of the Ramair to seal it to the scoop. The unit costs $300 unfinished with free shipping. The three throttle body holes were off so I had to glass over and drill out three new holes. the fit now is perfect. No more noise from the throttle bodies (except growl when wide open)!
