There is a differece. The best way to tell is to check the intake side of the filter. If there is a flange extending from the inner diameter then its an SVT model. The flange serves as a mounting point for the blue rubber hose which the SVT version is supposed to come with. The hose connects the intake side of the KKM to the fender well. Non-SVT 2.5's do not connect to the fender well and do not have a rubber hose mounted to the intake side, thus there should be no flange. I have one on my SVT, and my fiancee has one on her Cougar (non-SVT). As far as I know, no SVT versions had a blue end cap.

Hope that helps. If you'd like, I'll take some pics.
