But aftermarket CAI allow more airflow. And some incorporate the inlet tube AND a closed air box, like Airaid's kit for the 15. Also, there are RWHP gains from adding these aftermarket CAI over stock...so you can't argue with number.
If the Airaid is what you were referring to I take it back as it is the only after market cold air kit I have seen. The rest are hot air intakes.
