Can we make the airflow cleaner than otherwise? Cleaner enough to be worth the effort?
In my car, Honda went through some lengths to direct the air which passes through the radiator, out through the wheel wells rather than the rear of the hood or the bottom of the engine bay. Presumably there was a reason for this, but I have no data or facts to support this.
