I've noticed that my MOPAR CAI Air Box has a side opening window, I suspect that this allows air to escape! will it help to seal this window? and how will I do that?
Keep in mind, on a Naturally Aspirated engine (Or anything that breathes for that matter) The lower pressure areas are filled not because of suction but because air at normal atmospheric pressure rushes in to fill the void. You don't want the engine having to suck air in. That's like trying to inhale with a gas mask on and the engine will have to work just to get air. You want as open and free of a path as you can get which will allow the air to rush into the cylinders filling the low pressure areas without any energy being expended.Also I thought the more compact and closed the air box the faster and better suction will be!
Nope. Look again. The front is designed to channel cool through the radiator, but also through openings on either side of the radiator. Most of this air comes from the lower scoop. It comes in right next to the headlight assembly. It's this way on both sides. It was designed this way for a reason.Actually the air box is located right behind the headlights so there is no real cool air flow from the front grills coming in, the radiator is blocking the full grill area.
