My brother juss bought an RSX type S...someone told me dat u have to cut/move windshield water tank under the hood to fit an AEM CAI...is dat true?

 

Yes it is true. You have to relocate the windshield washer fluid tank from the driver side to the passenger side because the filter will not fit if you don't. You also have to cut a piece of the driver's side wheelwell so that the intake piping will fit.

An alternative option is the Injen CAI which only needs cutting of the wheelwell, as they provide you with another, smaller, windshield washer fluid tank.

Hope this helps.
