Set of 2 KOHLER 12 050 01-S Engine Oil Filter

What It Is

This is a set of two OEM KOHLER 12 050 01-S oil filters designed for Kohler Command, Courage, and Pro series engines found on residential and commercial zero-turn mowers, tractors, and walk-behinds. It replaces standard spin-on filters for routine oil changes.

Fitment & Compatibility

• Check your engine model: Fits Kohler engines with part number 12 050 01-S (also cross-references to KOHLER 12 050 01, 2509901S, and 1205001S). Common on Command CV series (CV15-CV740), Courage SV series, and Pro series (CH, CHL, CHS).
• Not universal: Does not fit Briggs & Stratton, Honda, Kawasaki, or older Kohler K-series engines without adapter. Verify your engine’s oil filter thread size (3/4”-16) and gasket diameter (~2.6”).
• OEM vs aftermarket: This is genuine Kohler, not a generic. If your mower manual specifies Kohler 12 050 01-S, this is the direct replacement. Aftermarket options (e.g., Stens 130-048) are cheaper but may not have the same bypass pressure specs.
• Measurement check: Filter height is ~3.2”, diameter ~2.9”. Ensure clearance in your mower’s filter mount area (some tight engine bays may require a shorter alternative).

Key Things to Know

• Quality: OEM Kohler filters have a silicone anti-drainback valve and high-efficiency media. Better than cheap aftermarket filters for extended oil change intervals (100+ hours).
• Installation difficulty: Easy – hand-tighten only (1/2 to 3/4 turn after gasket contacts). Over-tightening can strip the mount or cause leaks.
• Common gotcha: Some Kohler engines use a different filter (12 050 02-S) for larger displacement. Double-check your engine’s spec plate; the 01-S is for most CV/SV series but not all.
• Set of two: You’ll have a spare for the next oil change. Shelf life is several years if stored dry and cool.

Should You Buy It

If you own a Kohler Command, Courage, or Pro engine mower and want hassle-free, reliable filtration with zero compatibility guesswork, this set is a solid buy at $20. It’s ideal for DIY owners who change oil annually and prefer OEM quality over cheaper aftermarket filters.
