Stens Air Filter 056-030 for Tecumseh 35066

What It Is

The Stens Air Filter 056-030 is a direct replacement for the Tecumseh 35066 air filter used on single-cylinder, small-engine lawn mowers, tractors, and snow blowers. It traps dirt and debris before they enter the carburetor, protecting engine performance.

Fitment & Compatibility

• OEM Reference: Replaces Tecumseh 35066 and Stens 056-030. Also cross-references with Oregon 25-030 and Rotary 13042.
• Engine Fit: Fits Tecumseh engines with the 35066 filter housing—commonly on LEV, LV, Enduro, and XT series engines (e.g., LV195EA, LEV120).
• Measurements: Check your old filter’s outer dimensions: this one is roughly 4.75” x 3.25” x 1.25” (L x W x H). If your filter is larger or smaller, it won’t seal.
• Machine Check: Works on most walk-behind mowers, riding mowers, and snow blowers using a Tecumseh 35066 filter. Not for Briggs & Stratton, Kohler, or Honda engines—verify your engine model number before buying.
• Dual vs. Single: This is a single-element foam filter. Some Tecumseh housings use a dual-element setup (foam + paper); this replaces only the foam layer. If your housing expects a paper element, you’ll need a different filter.

Key Things to Know

• Quality: Stens is a reliable aftermarket brand. Foam density and fit are consistent with OEM—no trimming or mods needed.
• Installation: Tool-free; just pull the old filter out and press the new one into the housing. Takes 30 seconds. Make sure the housing clips or screws are fully seated to avoid unfiltered air leaks.
• Maintenance: Foam filters can be washed in warm soapy water, rinsed, and re-oiled (use foam filter oil). Replace every 25 hours or annually, whichever comes first.
• Gotcha: If your engine runs lean or surges after install, the filter may be slightly too dense for your carburetor. This is rare, but try running without the housing cover briefly to test.

Should You Buy It

Yes—if you need a direct, affordable replacement for a Tecumseh 35066 foam air filter on a mower, tractor, or snow blower. It’s a solid value at $9, with easy installation and proven reliability. Avoid it only if your engine uses a dual-element housing or a non-Tecumseh brand.
