There are endless ways to do it... But there is only so much frontal air to grab.. and only so much space in the engine bay to run pipping to the intake compartment.
The Jim C. Pretty much gains its air from up under the car... some have routed or modified their brake ducts up to the intake compartment... its all on what you think works best... but for your interest.. YES.. it is possible to rout that stuff to the intake compartment.. or a Jim C. intake.. to simulate forced induction to the air filter.
