if it still has the original valve covers, there should be the barcode + vin on the driver's side valve cover near the #1 coil pack. (At least, that's where I found it on my '13 300C 5.7.)


Otherwise, the big giveaway should be the intake itself. Truck intakes have the throttle body facing upwards, cars have the typical forward-facing throttle body. 6.4's will face off to the side.
