I needed a cheaper filter %26 pre-filter for my new American Made Grasshopper Model 100 41" wide zero turn mulching mower with Briggs %26 Stratton 25 HP CXI 2500 model 440000 engine operating frequently at 100 F and up to 113F in Kaufman, Texas. 1) This Paper %26 rubber Air filter exactly matches the dimensions of the B%26S engine manuals page 12 listed 798897. 2) This Foam pre-filter is twice thicker than the original dimensions of the B%26s engine manuals page 12 listed 593217 and is so thick as to increase the pre-filter outer diameter to exceed the inside diameter of the engines tubular plastic air filter receiving port and jams resulting in the need to discard remove the pre-filter for no protection!!!!! or a thinner OEM foam pre-filter to maintain filter protection
