I am trying to find an Oxygen Sensor for my 2008 Itasca Suncruiser 38T VIN 5B4MPA7GX83431516.
Service center is asking is it a 4600.
It has the Workhorse 8.1Liter with a w24 chassis. Will your part number 12572706 work? ( David Wingfield, 03/11/2019 )

Yes this is the correct oxygen sensor for your VIN.
