Looks like a cataloging error.This is what I am faced with:
2017 Ford F-150 Turbocharger - Driver's Side (LH) HL7Z-6K682-A | TascaParts.com
2017 Ford F-150 part # HL7Z-6K682-A - Turbocharger - Driver's Side (LH)www.tascaparts.com
2017 Ford F-150 Turbocharger - Passenger's Side (RH) HL7Z-6K682-C | TascaParts.com
2017 Ford F-150 part # HL7Z-6K682-C - Turbocharger - Passenger's Side (RH)www.tascaparts.com
See how they both say DRIVER SIDE.
Ford eCat lists HL7Z-6K682-C as the Right Hand (passenger) side. It is a superseded number from the original HL7Z-6K682-B.
I’d call Tasca to confirm.
