One more time . You need an air sorce void of under hood engine heat to make the most power . Do you know what an IAT is or how it works ? Just because you have an open eliment with no silencer that make loud voom voom sounds doe's not mean you are makeing more power . Modern cars and trucks (your H2) have a computer . The IAT will send a signal to your computer and adjust for hot intake . Cool air is better than hot air to make power .Even on non computer cars this is true .As far back as 1957 Chevrolet knew this . Look up 1957 Chevrolet Air Box Corvette . Drawing /ramming cold air in an engine gives the best power .
This is a fact
Choose to beleive what you want ,It won't change the facts .
