It appears that my N/A engine does not have air pump system as shown/described from the info on the Bay13 webpage. I printed out the instructions for the change, but noticed that based on the pictures, my car doesn't seem to have the components as shown. For starters, there is no SAS valve present at the rear of the engine over top the silver hot-air hose, nor is there a intake hose from the pump entering the the front of the airbox as shown on the first pic and others. Were there some models excluded or have a different system. I have checked the air pump postings on the board and it appears that everyone has the pump system. What is up?
