But then I thought that there must be an ideal hot temperature for engine efficiency before it looses too much power or causes problems.
What kinds of HAI temps are beneficial?
By the way im not following through on some odd hot ram air intake. Its just the thought that led me to the question.

There was a member named lovemysan that ran his HAI up to 190 degrees F. At that temperature he said his Saturn S-Series 1.9 liter 4-banger started to have driving problems.
I don't think I've gotten higher than 160 degrees F, but I am not positive.
More details from lovemysan :

A sealed grill block with passages to the radiator would be best. The HAI will reduce underhood temps. Limit IAT temps to not more than 190, you will loose power and mileage. Do not exceed 200f coolant temp, again you will loose power and mileage. I found IAT 150-180 and coolant at 190-195 to be most efficient.
