What It Is

The Stens Air Filter 100-222 is a replacement foam pre-filter for small engines, designed to trap coarse debris before it reaches the main paper filter. It fits Tecumseh engines commonly found on push mowers, riding mowers, and lawn tractors from brands like Craftsman, MTD, and Murray.

Fitment & Compatibility

Before buying, verify your engine model against the listed Tecumseh models: ECV100, LEV90, LEV100, LEV115, OVRM60, or TC300. Also check OEM part numbers: 33342, 63087A, 35066, 740019B, or 740095. This is an aftermarket part—not OEM—so measure your existing filter’s outer diameter (approx. 2.75 inches) and thickness (approx. 0.75 inches) to confirm fit. It will not work on engines with a different air box design or non-Tecumseh brands like Briggs & Stratton or Kohler.

Key Things to Know

• Quality: Stens is a reputable aftermarket brand; foam density matches OEM specs for most users, but some report slightly looser fit than original.
• Installation: Tool-free—just remove the air box cover, swap the old foam, and reinstall. Clean the air box of debris first.
• Maintenance: Wash in warm soapy water every 25 hours of use, let dry completely, then lightly oil before reinstalling. Running without oil reduces filtration.
• Gotcha: This is a pre-filter only—if your engine uses a combined foam-and-paper element, you still need the main paper filter (sold separately).

Should You Buy It

Buy this if you need a budget-friendly, direct replacement for a Tecumseh foam pre-filter on a mower or tractor used for regular residential cutting. It’s a solid value at $7.84 with strong reviews, but skip it if your engine requires a full paper element or if you demand exact OEM fitment—the slight dimensional variance may cause a loose seal in some air boxes.
