Not very easy to photograph in a dim garage but this is the location of the factory air in

Bottom of the air filter box, quite a small oblong hole & only a couple of inches above the Clutch bellhousing which gets hot



and close to footwell bulkhead, which can't be good for a smooth flow of cool air



The airbox is pretty simple Ford item, the throttle body is just out of shot under the bonnet hinge
