12572706 - Workhorse Oxygen Sensor

12572706 - Workhorse Oxygen Sensor

Part# 12572706


  • 2001 - 2010 Workhorse 8.1L Engines
  • All Workhorse Chassis with a 8.1L Engine

*(On pre-2003 models you may be required to modify the electrical plug by trimming a small piece for proper fitment)

Brand new Workhorse part for 8.1L engine. A bad oxygen sensor can be detected by either a check engine light or by a sudden loss of fuel mileage and/or power.

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. ( Support )
I would like to verify fit for my 2004 Winnebago/Workhouse chassis. Also, I can receive shipping only through UPS. Can you verify that the shipping method would be UPS? Thank you. J.C. ( J.C. Bristow, 02/03/2018 )
