the same model year and engine size? i have a 2001 crown vic and i put a 75mm throttle body on it but i need the upper intake plenum as well to match the increased size of the throttle- trickflow makes this ported plenum but they sell it as a plenum for the ford mustang 4.6l 2v. the mustangs air intake is toward the passenger side of the engine bay and my vic's is toward the drivers side.
