The SVT 'tours have a large plastic delector to force air through the radiator, not spill out around it, and that deflector covers the entire underside of the front of the engine compartment, keeping you from getting to the foglights, radiator drain plug, oil filter, etc.
Those retainer plug things that keep the access door in place are hard as snot to get out... i think taking the entire deflector down would be easier
