The ones that have a straight entry(no angled like some of the aftermarket ones) into the middle of the plenum like on an MR2 turbo are much worse. The center cylinders get so much more air than the others that they lean out a lot and engine up burning up those pistons with some mods over stock. I wonder if that crazy AMS F1 intake gives fairly equal distribution with it's design.
