Like Nicholas said, your emissions are just that...EMISSIONS, something your car is emitting, they don't test the quality of the air going in the motor(that's only as clean as the air you breath)but the chemicals in the gases that come OUT of your motor. I wouldn't sweat it in the least bit.
You may also want to consider the effect winter air will have, it will be extremely cold and dense. maybe even too cold. Best way to know is just test it out and see.
Once I get my car back I'll be working on a custom ram air intake to mate with my KKM intake. We'll see how that goes. Good Luck!
