## Questions & Answers

**Q: Is this a Briggs and Stratton branded filter? Thanks**
A: 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".

**Q: 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?**
A: 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.

**Q: Is the size exactly 5-1/4 x 4-1/2 x 1 in. ?  The production at listing says different.**
A: I just went down in the basement and measured it, and yes, the dimensions are exactly what you said.  Good luck!

**Q: 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!**
A: 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.
