Maintaining For 20 Years

I've used the same mower for 20 years now and change the filter once or twice a year. Can't beat OEM quality direct from Briggs along with synthetic oil. Great for filtering dusty conditions while keeping the engine cool. Make sure your filter number matches what your manual recommends.

A lawnmower's best friend

Lawnmower needed a new filter because the old one was full of dirt which prevented the lawnmower from working properly. I purchased this filter and now the lawnmower works great. Filter was easy to install and saved me from a costly repair job or new lawnmower. I am delighted I decided to buy this filter.
