Unfortunately no, that's why the rx300 has cut outs on the bottom of the bumper to enhance air flow, if you would like you can install a small 7 or 8" auxiliary cooling fan witch has about 650-750 cfm's. That should be plenty of air flow to be ok all you have to do is wire it up to a relay and then to a on/off switch so you can have it on or off as you please
