Do you know what code the car threw?
The computer cannot detect a deformed airbox specifically. What it can detect is a lean condition if it's bad enough. That lean condition can be caused by an number of things and in this case the dealer tracked it down to a deformed air box that was not sealing.
No, they did not show me the air box and I didn't ask. I wasn't all that interested. They got me in there quickly, fixed the car quickly and I was on my way. So far no more check engine light and that's all that matters.
I don't remember the code exactly.
