Frist of all not sure if this is the right place for the post.

So i have a 09 chevy cobalt 2.2 lap, so i turbo this car, ran it for a while sold the turbo parts, and now I'm putting back to stock.
my issue is i dont have all of the sair system anymore, i at lest have the check valve and all the parts the mount to the head. now im wondering if i can just plug the check valve in and the car will think the sair is working or would i have to get all the sair stuff put on agian.
