4 Pack 52 050 02-S Oil Filter Compatible with Kohler M18 M20 SV715 SV725 SV735 CV13S CV15S CV22S Engine 52 050 02 5205002S 52 050 02-S1 Pro Performance Lawn Mower Oil Filter

What It Is

This is a 4-pack of aftermarket oil filters (model 52 050 02-S) designed for Kohler gasoline engines used in residential and commercial lawn mowers, tractors, and zero-turn mowers. It replaces OEM Kohler part numbers 52 050 02, 5205002S, and 52 050 02-S1.

Fitment & Compatibility

Before buying, check your engine model—not just mower brand. This filter fits Kohler Command, Courage, and Pro series engines including:

• M18, M20 (single-cylinder)
• SV715, SV725, SV735 (V-twin)
• CV13S, CV15S, CV22S (V-twin)

Verify your engine’s model number (stamped on the blower housing or valve cover). This filter has a 1-inch thread diameter (3/4-16 UNF) and a gasket O.D. of about 2.4 inches. It is not compatible with Kohler KT or K series engines (which use a different thread). Measure your old filter’s thread and gasket size if unsure. Aftermarket fitment is generally fine, but avoid this if your mower requires a specific OEM-only filter (rare for Kohler).

Key Things to Know

• Quality: Aftermarket but meets OEM specs. Users report no leaks or fit issues. Not as heavy-duty as premium brands like Wix or Mobil 1, but adequate for standard oil change intervals.
• Installation: Hand-tighten only—1/2 to 3/4 turn after gasket contacts the engine. Overtightening can strip the thread or warp the gasket.
• Gotchas: Check for debris or shipping damage in the pack. Some users note the filter is slightly shorter than OEM (about 0.2 inches), but this does not affect function on most mounts.
• Value: $17.99 for 4 filters (~$4.50 each) is a strong deal compared to $8–12 per OEM filter. Ideal for seasonal mower owners.

Should You Buy It

Buy this if you own a compatible Kohler engine and want a budget-friendly bulk option for regular oil changes. It’s not for high-hour commercial use or if you prefer premium filtration (e.g., synthetic oil, extended intervals), but for standard residential mowing, it’s a solid, cost-effective choice.
