595663 Air Filter Base, 595660 Air Cleaner Cover & 799579 Air Cleaner Foam Filter Replacement for Briggs Stratton 450E 500E 550E 550Ex Engine Lawn Mower

Fit the mower perfectly

I had to install a new carburetor, so I figured I would replace my filter base which was also just not in good shape. I very carefully removed the original, paying attention to the order of things as I went. The replacement fit perfectly, was really easy to put on, feels to be of excellent quality, and is working great. Very happy I did this.

The prime pump button on the old B&S lawn mower engine was loosing it's power. This one fit perfectly and works well.

Primer bulb isn’t installed. A 15/16” or 24mm socket fits the plastic ring and helps pushing-snapping the bulb ring in place

Its complete with everything you see, just make sure your implement is a B&S, or this may be kind of universal, but mine is a little cheap push mower I bought from Lowes to mow a little area that I cant get to with my Zero Turn, it cuts very well though.I took a chance and ordered what little info I could find on my engine-Briggs and StrattonBolens450 E - 125.Fit like a champ.

I just needed a spark plug and an air filter so this kit made more sense than buying them individually. But after getting it, the other parts in the kit (primer bulb and plastic covers) seemed to be as good as the OEM parts and helped me realize how bad shape my primer bulb was in!The spark plug was a no-name one, but it worked perfectly and my mower fired up immediately after changing the old plug out.The filter and primer bulb seemed to be of good quality too. I’d buy this kit again if I needed it.

Perfect fit on my Craftsman 21 inch push mower. Use the model and serial number to ensure you are ordering proper assembly.

Works but definitely not factory Stihl products
