What It Is

This is a 4-pack of oil filters (model 12 050 01-S) designed for Kohler engines commonly found in lawn mowers, tractors, and zero-turn mowers from brands like Cub Cadet, Craftsman, Troy-Bilt, Toro, and Gravely. It replaces OEM part numbers 12 050 01-S1, KH-12-050-01, 12-050-08, and KH-12-050-08.

Fitment & Compatibility

Before buying, confirm your engine is a Kohler single-cylinder or V-twin (e.g., Courage, Command, or Pro series). Check your current filter’s thread size—this filter uses 3/4"-16 threads and a 1-inch hex. Measure the canister diameter (approx. 2.5 inches) to ensure it clears your engine housing. Avoid using on Kawasaki, Briggs & Stratton, or Honda engines unless cross-referenced. Verify your model number against the OEM list—this is an aftermarket filter, not genuine Kohler, so fitment varies on some older or odd-sized housings.

Key Things to Know

• Quality: Aftermarket, not OEM Kohler. Some users report slightly thinner gaskets or shorter lifespan—change at recommended intervals (every 50 hours or seasonally).
• Installation: Hand-tighten only (no wrench needed). Over-tightening can damage the gasket or housing. Pre-fill with oil before installing to prevent dry starts.
• Common Gotchas: The 4-pack is a good value but check your engine’s oil filter location—some compact engines have limited clearance. If your OEM filter has a bypass valve, this aftermarket version may lack one, which can affect cold-weather performance.
• Return Policy: If it doesn’t fit, return the whole pack—single filters aren’t sold separately.

Should You Buy It

This 4-pack is a budget-friendly choice if you own multiple Kohler-powered machines or plan to stock up for several seasons. It works well for most standard applications, but if you need exact OEM specs (e.g., for a critical commercial mower or cold-climate use), stick with genuine Kohler filters. For homeowners with a single tractor, a single filter might be more practical.
