Bobby 3/23/2011They put it in several places on the car one is usually on the top of the engine it says it. It also will say it on the vehicle info sticker that all manufacturer's put under the hood and on the side of the drivers front door. unless someone removed those at some point they should be there. Check on the under side of the actual hood, its usually labeled engine family. as for what sub model you ex dx si? that is on the back of the car if the emblem has fallen off then check your registration it should be on there.
