The cai filters will pull enough air with those dividers in place as the dyno tests done from members were done with the dividers in place.
avg was 5-7 hp compared to the Stillen Gen3's
I personally ran those intakes a few years ago and had no breathing issues to warrant removing the guides.
Those dividers are meant to keeping the volume of incoming air thru the front grills moving past the radiator and into engine bay.
You wont notice the change but thats what they're there for.
I know when I pulled off my bumper last time I noticed one of them was bent around and not pointed toward the front so I straightened it out.
Anyway just a reply enjoy the intakes and avoid deep puddles in the winter/raining season
