If the option is to vent fresh air to the filter or to the intercooler then vent to the intercooler. Decreasing charged air temperature is the job of the intercooler.

If you have the option to do both this is what I did. I built a shroud enclosing the intercooler with the back left open so that the fan also pulls air right through the area where my little filter sits. I could lay my hand on it at idle and feel the air pulling through the intercooler and the open vent for the air filter. I later added louvers to the other side for use in the hot Alabama summers.
