This is a genuine OEM sourced replacement air cleaner cartridge commonly utilized on Briggs and Stratton engines. It installed to filter our dust and other contaminants from entering carburetor and the engine. Please note, this pleated paper filter is sold individually. Keep in mind that the foam pre-cleaner is sold separately.
Replacing this air cleaner cartridge is a simple task that should only require a wrench.

I ordered this part for my 35 year old generator. Never expected to find it
It was an exact replacement.
When I need a part for any equipment (i.e. table saw, chop saw, lawn mower, generator, chain saw etc.) Replacement Parts.com is the first stop.
Thank you

I thought I would never find this air filter; a 35 year-old motor.
It fit perfect, and appears to work just fine. I bought a second one as a spare

It's an air filter, changing it is a no brainer!
This is for a Craftsman mulcher with an 8 hp briggs and straton engine. Others would not even show me a parts list on their site. I'm glad you're around.

I rebuilt the carb and had probs with continued float valve leakage. Disassembled and reassembled 4 times. Quit for the day. Then discovered a brand new complete carburetor ($34) cost less than the rebuild kit and parts. Ordered and installed easiky. All is good now. Learned a lesson.
