When the infamous CGS hot air intake was the rage a few years ago, I did exactly that. Setup a digital thermocouple to take measurements at a few points. Air temps were in the 30 - 50 degrees hotter range when the air was sourced underhood instead of the fenderwell. SAE computations indicated a loss of 4 - 6 HP with that. I also confirmed that on a dyno. Air doesn't do "funny things". Changes in air density due to temperature is a known scientific fact.

BTW, the stock intake system is NOT restrictive either. Have data to prove that, too.

But from what I've read online about hot air intakes, you lose hp, but gain mileage.... Is that correct?

I agree with GreyBeard. If an engine is more efficient, it will make more power. So, if the car loses horsepower due to higher underhood heat, then you'd have to press the pedal harder to accellerate the same or maintain a constant speed. That would logically burn more gas. I have long heard that making an engine more efficient (with more horsepower) will also give it more mileage. Just my 2 cents worth, and I am no expert at anything. God Bless, Marc

Air does funny things was in referance to airflow not density......or temp.......a moving vehicle will flow air differently then a stationary one....usually
