No OEM reference numbers are supplied for this part, so buyers should verify fitment using part number 318678 and the specific engine code. Check the existing turbocharger for matching part numbers and physical dimensions. Confirm the engine type (SAA6D125E-3, SA6D125H, or P139) and vehicle model before ordering.
