🛑 Buyer’s Verification Notice
Please Note Before Purchasing: However, Caterpillar and Perkins 4.4L engines use multiple turbo charger variations. Although they look identical, they have different internal trims and wastegate calibrations. Therefore, please do not order based on equipment model alone.
Always verify that the part number on your original turbo’s metal ID tag matches 2674A825 or 326-9153. If you need any assistance, please contact our PHESSIO technical support team with your Engine Serial Number (ESN) before buying!
