What It Is

This is a complete tune-up kit for Kohler Courage/SV series engines, containing one air filter, one oil filter, and one spark plug. It’s designed for routine maintenance on lawn tractors and zero-turn mowers from Cub Cadet, Toro, and similar brands using specified Kohler engines.

Fitment & Compatibility

Required engine models: Kohler SV470, SV471, SV480, SV530, SV540, SV541, SV590, SV591, SV600, SV601, SV610, SV620.
What to check before buying:

• Confirm your engine’s model number (stamped on the valve cover or blower housing).
• This kit is not for Kohler Command or other series—only the Courage/SV line.
• OEM equivalent: replaces Kohler part numbers 25 083 02-S (air filter), 12 050 01-S (oil filter), and 25 132 15-S (spark plug).
• Deck size or brand doesn’t matter—only engine model.

Key Things to Know

• Quality: Parts are aftermarket but match OEM specs. Spark plug is pre-gapped, but verify gap (0.030”) before installing.
• Installation difficulty: Easy—basic hand tools (socket wrench, screwdriver). No special skills needed.
• Common gotcha: The air filter is foam; do not oil it. The oil filter spins on by hand—tighten 3/4 turn after gasket contact.
• Kit completeness: Includes everything for one full tune-up. No extra gaskets or crush washers.

Should You Buy It

Buy if you own a Kohler SV-series engine on a Cub Cadet, Toro, or similar mower and want a budget-friendly, one-stop tune-up kit. It’s reliable for routine maintenance, but skip if you need OEM-only parts or have a different engine series.
