since im upgrading, should i replace the air intake as well?
dyno results show that mkiv supraswith the bpu and no intake system dyno about the same as those with either a k&n or a hks super mega flow (the gain is minimal).higher horsepower cars will benefit more from the installation of an air intake system.if you must upgrade, the max air airbox with intake has been given high praise by several list members.one upside for some if you get a cone filter upgrade is you will hear a lot of new noises from your engine if you like that sort of thing.
