What It Is

This is a two-pack containing an air filter (20 083 02-S) and an oil filter (52 050 02-S) designed for Kohler Courage single-cylinder engines found in many riding lawn mowers, typically 15–22 HP. It’s a direct replacement for routine 100-hour maintenance on tractors like Cub Cadet, Husqvarna, Craftsman, and Troy-Bilt models using Courage engines.

Fitment & Compatibility

Before buying, confirm your engine’s model number (e.g., SV470, SV480, SV530, SV540, SV590, SV600, SV610, SV620, SV710, SV720, SV730, SV740, SV750, SV760). This kit fits the Courage series but not the Courage Pro or Command series. Also check your mower’s deck size is irrelevant—only engine model matters. OEM cross-references: KH-20-083-02-S, KH-20-883-02-S1 for the air filter; KH-52-050-02-S for the oil filter. Measure your old air filter height (approx. 2.5 inches) and oil filter thread size (3/4-16) to be safe.

Key Things to Know

• Quality vs. OEM: Powtol is aftermarket; most users report it matches OEM Kohler filters in fit and filtration. The air filter uses pleated paper, not foam—do not oil it.
• Installation difficulty: Easy—air filter slides into housing without tools; oil filter hand-tightens only (1/2 to 3/4 turn after gasket contacts). No special tools needed.
• Common gotcha: The oil filter is not interchangeable with Kohler’s 12 050 01-S (shorter filter). Verify your current filter’s height (this one is ~3.1 inches). Also, the air filter has a pre-formed foam gasket—ensure it seats flush to avoid unfiltered air leaks.
• Frequency: Replace both every 100 hours or annually, whichever comes first. Running a dirty air filter can cause rich fuel mixture and engine surging.

Should You Buy It

If you own a riding mower with a Kohler Courage engine and want a cost-effective, reliable replacement for routine maintenance, this two-pack is a solid choice. The price is roughly half what you’d pay for two OEM filters, and the 4.7-star rating from over 1,300 buyers confirms it works. Skip it only if you need a different oil filter height or have a non-Courage engine.
