I see that your location is in CA. I recommend F sport for it being carb approved. Injen is louder but its not carb approved and in the summer, it will suck in hot air. I used to have a Injen intake on mines but switched over to F Sport.
The F Sport if you want true CARB exempt. I had an injen and I bought an F Sport CaRB sticker and kept it in the glove box in case I got pulled over and for smog. It costs $5 at the dealer. injen looks better to me too with the exposed filter.
