You just created a noise generating hot air intake. I think the Nissan Engineers have a better grasp than you do on intake air temperature. Not to mention you have a CVT and 2.5L so what in the world would you possibly gain even if a so called CAI did exist.
I know some people that have cold air intakes on their vehicles. Almost without exception theyr'e 18-25 years old and trying to impress their friends. Just children, many of those same kids have the "little wennie" mufflers on their vehicles.
