This Filter replaced the original on my Cat 3126B engine in my Class A Motor Home with a Freightliner Chassis perfectly. Old filter was a Farr 114810003.

Was easy to find this filter to replace old one by part No.. Fit like a glove, better than old one. Was shipped and received as promised.
Art Schmitt, Colorado
Great product and great service. I use this filter in a motor home with Cummins diesel engine. After years of use I decided to replace the filter and ordered from the website after talking with rep to be sure I would be getting the same filter. Filter was delivered quickly and I was able to replace the old one while visiting an RV park during our travels.
