Getting enough air to those big turbos I have was a problem with the stock intake system. Tested the car out last night for the first time (I scared myself lol) with the new intake and it's certainly making a difference now I think the stock intake system is fine on stock turbos but when you go larger, you don't want to be starving turbos for air Stalling etc....
