Review: Great Replacement Air Filter – Easy Installation & Improved Performance - I recently purchased this filter for my lawn mower, and I’m really pleased with the results. Pros: Super Easy to Install: Installation was a breeze. I was able to replace the old, clogged filter in just a few minutes. No tools were necessary, and it fit perfectly into my mower’s air filter compartment. It was a straightforward swap, even for someone like me who’s not very mechanically inclined. Improved Mower Performance: After replacing the air filter, I noticed an immediate improvement in how my lawn mower runs. The engine feels smoother and more responsive. It starts up easier, and I haven’t noticed any hesitation in power while cutting. Durability & Quality: Briggs & Stratton is a trusted brand, and this filter certainly lives up to their reputation. The material feels sturdy, and I can tell it will last through multiple mowing seasons if properly maintained. Perfect Fit: It’s the exact replacement for the filter in my model (make sure you check your mower’s specs for compatibility). There’s no guesswork, and I’m confident it’ll work with other compatible models. Cons: None So Far: I’ve been using this filter for a few weeks now, and I haven’t encountered any issues. I’ll update my review if anything changes over time, but for now, everything is running smoothly. Overall Thoughts: If you're looking for a high-quality, easy-to-install air filter for your Briggs & Stratton-powered lawn mower, this filter cartridge is an excellent choice. It significantly improved my mower’s performance, and I don’t expect any issues with it. Highly recommend for anyone in need of a quick replacement! Tip: Make sure to regularly check and clean the filter, especially if you mow in dusty or debris-heavy areas. A clean filter will keep your mower running at its best.
Review: Perfect fit - This is a quality filter. Fits perfectly and keeps engine clean. Highly recommended.

## 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.
