I added the red for emphasis

a hot air intake on a diesel would be a bad idea since it could raise the exhaust gas temps too high. high EGTs is murder for a diesel.

HOWEVER a hot air intake on a gas engine can help reduce pumping losses by allowing a wider throttle opening. His car has no throttle, hence the confusion.

I know my Maxima has OEM wrapped tailpiping; I'm sure they also used some sort of a metal that resisted rusting, but either way, I have no issues with tailpipe leaks after 12 years of the car running and over 220K miles
