If you want the injen get the injen, i would just look into swapping out the filter element for a powercore.
Donaldson says that the Nanofiber is far superior to anything else for a material to filter out dirt. INJEN uses Nanofiber for filter material in the Raptor CAI.
I think the Powercore is Nanofiber as well but not sure on that one.
I am old school and hate plastic performance parts. I work on a lot of Hot Rods and Muscle cars and its a big taboo to put plastic parts under the hood. I feel the same way about my Raptor. If I can find a better CAI then the INJEN I will give it a try, but it just cant be plastic.
INJEN makes a lot of different designs including sealed box types with fine wire mesh for openings, unfortunately only one for the Raptor so far.
