## Description

desertcart.com: Air Cleaner Replacement Foam Filter 799579 fit for B.S. Engine Air Filters Spark Plug compatible with Briggs and Stratton Lawn Mower : Patio, Lawn & Garden

Review: Seem to work, less expensive than the OEM replacement part - The filter is a piece of fitted foam rubber. For such a small part, I considered buying the OEM part (which is what I did on the actual carb), but on this part, I just bought a 3 pack of no name filters, for about the same price I would have paid for one OEM brand. Have a couple of spares might make actual maintenance a bit easier on my part. (OLD filter was ridiculously deteriorated, which was totally ON ME. Had I replaced more often (at all), I might have saved the cost of the new carb I had to buy.) These filters fit fine and mower started/ran fine after replacement (of filter and new carb). Good part, good seller.
Review: Great Filter Replacement - Can't speak for the sparkplug I didn't know was included but the foam filter was a perfect fit and my 13 year old Craftsman mower is running better now.
