ford has their system set up to play with the turbulence.... cai/sri are a straight shot.... that's why many headers are not one straight shot anymore, a lot of them twist.Can someone explain this? How can a stock air box configuration be better flowing that a straight walled tube? I'm baffled by it.
eh all coompanies nowI know on the Duratec cars Mazda Engineers worked the resonators , or well every piece of the intake to get the smoothest air and most amount of airflow for them. That's why most of the newer foci drive like a fat pig when you mod them, because your inbalencing all of the engineering for some toothless Joe at a intake factory bending a pipe that fits your car.
It helps to really think about WHY things are done the way they are.Well they sure don't look like an engineered piece of plastic.
