14 083 15-S 14 083 16-S Air Filter for Kohler XT650 XT675 149CC 6.5 6.75 Engine Lawn Mower Toro 20371 20370 Lawn Boy 149CC Air Filter Pack of 3

What It Is

This is a three-pack of aftermarket air filters (models 14 083 15-S and 14 083 16-S) designed to replace the OEM filter on Kohler XT650 and XT675 engines (149cc, 6.5–6.75 hp). It fits Toro 20371 and 20370 mowers, plus select Lawn Boy 149cc models. Use it for routine maintenance to protect the engine from debris and extend engine life.

Fitment & Compatibility

Before buying, confirm your engine is a Kohler XT650 or XT675 (check the engine model number stamped near the air filter housing). This filter is not universal—it will not fit Kohler Courage, Command, or other series. Check your mower’s model number (e.g., Toro 20371, 20370; Lawn Boy 149cc) against the listing. The filter measures roughly 3.5 x 2.5 x 1.5 inches—measure your old filter to verify. It’s an aftermarket part, not OEM Toro, but it matches the OEM dimensions and port shape.

Key Things to Know

• Quality is adequate for the price – Users report similar filtration to OEM, but some note slightly thinner foam. For residential mowing, it’s fine; for heavy commercial use, stick with OEM.
• Installation is tool-free – Open the air filter cover, swap the old filter, and close. No screws or clamps needed on most models.
• Common gotcha – Ensure the filter is fully seated and the cover snaps tight. A loose fit can let unfiltered air into the engine, causing wear.
• Three-pack value – At ~$2.67 per filter, it’s a budget-friendly way to stock up. Replace every 25–50 hours of use or once per season.

Should You Buy It

If you own a Toro or Lawn Boy with a Kohler XT650/XT675 engine and want a cheap, reliable replacement for routine air filter swaps, this three-pack is a solid buy. It’s not for high-hour commercial use, but for home lawn care, it delivers good value and fitment.
