Description
Overview:
The Air Filter Base Gasket is a genuine Kohler part (OEM No. 12 041 09-S) that seals the joint between the air filter base and the engine intake. Made from durable gasket material, it maintains an airtight seal under heat and vibration to stop unfiltered air from bypassing the filter. This helps protect internal engine parts and supports clean combustion and stable running. Designed for Kohler Command Pro engines commonly found in construction and garden machinery, it is a direct fit for models such as CH11 and CH410. The gasket is a straightforward replacement during routine servicing and is a key item to restore proper intake sealing when the original gasket is worn, flattened, or damaged.
Key Features:
- Genuine Kohler part for assured compatibility and quality
- OEM number 12 041 09-S for a precise, repeatable fit
- Fits CH11, CH410, CH430, and CH450 engines
- Durable gasket material resists heat, fuel mist, and vibration
- Maintains an airtight seal to prevent dust and debris entering the engine
- Supports smoother running, better filtration, and longer engine life
- Correctly sized cut-outs align with the air cleaner base and fasteners
- Simple to install during routine air filter or intake service
Typical Applications:
Used on Kohler-powered equipment such as lawn tractors, ride-on mowers, generators, pumps, plate compactors, and other small plant and garden machinery. Ideal when refurbishing the air cleaner assembly or resolving air leaks that cause rough running or premature filter contamination.
