You can make a scoop that attaches to where the left radiator air deflector goes/is. I cut the deflector apart, grafted a scoop onto it, and reinstalled it. I attached a hose to the back and routed it up to the air filter area. It dumps angled across the length of the filter. Also the airflow pushes back any heat seep from the other side of the heat shield.
It makes a very nice forced, fresh air source to the filter area. When moving my IAT is always at ambient temperature.
