Thing is. for just any high flow filter. The engine computer compensates for it. so no real gain.
As for the cold intake. Unless you also open the exhaust. all that air coming in has no where to go. so once again. Little to no gain. To really make a difference you have to open both the intake, and the exhaust, and tune accordingly.
