It's there under the airbox. You can get at it from the inside with the filter out. Like Na 240s the flap fails in the hot position. So mine is hot all the time. As you say, with Kjet and the turbo it would not be a big deal if you were not trying to make maximum horsepower. But this car has been converted to LH 2.4 so I need to worry about cooking the AMM.

I suppose I could take the flap out and block off the hotside port.

I also meant to thank you Art. You were right on with your diagnosis of the 113 code awhile back. My AMM was the culprit. I would have tried one right away but I didn't have one. My parts source is about an hour away and I finally got there last week.
They also were quite sure that it was not the AMM, and thought it was a ground problem. After redoing the grounds they then thought it was the ECU. I finally talked them into putting in another Amm and the car went back to running perfect.
