What It Is

This is a dual-element air filter set (pre-cleaner and main filter) designed for Kohler Command PRO and Courage single-cylinder engines. It fits mowers, tractors, and zero-turn models using CV11–CV16S engines, replacing OEM part numbers GY20574, M92359, AM121608, and AM123553.

Fitment & Compatibility

Before buying, verify your engine model is Kohler CV11, CV12.5, CV13, CV14, CV15, CV16, or CV16S (check the engine shroud or decal). This filter is not for V-twin or larger Kohler engines. It matches air filter housing dimensions of 6.5” x 4.75” x 2.5” (main) and 3.75” x 2.75” (pre-filter). It fits most Cub Cadet, John Deere, Troy-Bilt, Husqvarna, and Craftsman mowers with the specified Kohler engines. Measure your old filter or housing opening—don’t rely on brand alone.

Key Things to Know

• Dual-layer protection: The foam pre-cleaner catches coarse debris; the paper element traps fine dust. Replace both every 100 hours or yearly.
• Easy install: No tools needed—just unclip the housing, swap filters, and re-clip. Ensure the pre-filter is fully seated inside the main filter to avoid air leaks.
• Check for oil contamination: If the old filter is oily or wet, you may have a crankcase breather issue—replace that first or the new filter will clog fast.
• Aftermarket quality: This is a non-OEM part. Reviews note it fits well, but the foam may be slightly less dense than Kohler original. Still works fine for residential use.

Should You Buy It

Yes, if you have a Kohler CV-series single-cylinder engine and want an affordable, drop-in replacement for routine maintenance. It’s a solid value for homeowners and light commercial users. Skip it if you need OEM-only for warranty or heavy-duty commercial use.
