Pop the fastners for the liner in the wheel well and have ur wheel turned so u can access the 2 bolts for the resonator. you'll have to use a 6" extention for a 10mm socket if i remmber rite. it takes a lil working with to remove (this is probly the most difficult part)

the rest of resonator should just pull out from the engine bay once the bolts are removed. with ur stock intake, removed all connections and loosen the bolts around and inside the intake box. the hosing should jsut pull rite out and the whole unit goes very easily. with the 2 piece, place the lower half in where the resonator goes, u might have to guide it down from the wheel well. once its down there u can attack the filter. for the upper half, attach it to the fuel injector and direction it to where the lower half is. in most 2 pieces there's a bracket thats a part of the CAI.

the bracket SHOULD line up with one of the holes from resonator or intake box that was once there. u can reuse the screws or use ones that might come with it. after that u can affix the 2 pieces together with the connector fitting and u should be set.
