Is this a Briggs and Stratton branded filter? Thanks

Received 5 unmarked filters, not Briggs and Stratton, from my order of 8-15-18, which I returned through Amazon's excellent returns policy. According to B&S, who I called, "all our filters are stamped with our name and product number on the sides".

I have a Toro model 20372 with 6.5 HP engine. The engine is made by Toro, not Briggs and Stratton, Tecumseh, Honda, etc. Will filter fit this engine?

to "cbow" and "nikko" and any others who answered "no" to my question.....you are all wrong!!!!!! this filter is a perfect fit for my mower described in my question. glad i checked locally. maybe in the future you could either give accurate answer or no answer at all to a question you don't know the correct answer to.

Is the size exactly 5-1/4 x 4-1/2 x 1 in. ? The production at listing says different.

I just went down in the basement and measured it, and yes, the dimensions are exactly what you said. Good luck!

i have a push mower .. briggs and stratton quantum power model #22545x92E .. about 15 years old .. 22" murray. i need an air filter .. please help!

Thank you for considering AMC Parts Store for your mower parts.This is a very popular air filter for smaller Briggs engines.However, to be sure, we will need the ENGINE model #, type, and code to research it for you.It may look something like 125K02-0126-01.
