Translation: it's not how deep you go, it's how tight it is on the sides
But seriously, on my IROC bumper, I'd used weatherstripping foam on the sides to control the airflow.

Many here are strongly focusing on the amount of air-space behind the cooler. I would say that it is MORE important to seal the perimeter of whatever size cooler you're using...even wth only 1/2-1" space behind it. It's the path-of-least resistance we're worrying about, and unsealed edges have ( IMHO) more of an effect than whether you have a small or large amount of structural stand-off *behind* the cooler ( that's still important though...but shouldn't be our primary focus).
