i was pulled over on the weekend by the state traffic task force, they poped my bonnet, looked at the pod filter, made sure it was secure, then they said ok your fine to go couldnt find the battery under the bonnet! to check the clamps on it. ha ha! lol but the rule is the pod filter has to be secured by a bracket of some type to stop it from moving around freely. if its already in a air box type thing, it should be fine.
