Sign up and check over at http://www.matrixowners.comA few members have installed a few CAI's over there on the new 2.4 litre, I do not remember what brand though.

I don't know any who have installed CAI,but I know a guy who installed a AFE short ram from an XB.The only difference is the vibramount mounting.The K&N says it will fit a Scion xB 08 and Matrix 09,with the 2.4,but the mounting still seems to be a problem.I've seen the mount and you can make something or just leave it off.
