What It Is

This is a paper air filter replacement (2-pack) designed for MTD, Cub Cadet, Troy-Bilt, and similar lawn mowers equipped with 140cc OHV engines like the 5T65RU, 5T65RUA, 5T65VUA, 1T65TU, or 1T65DT. It keeps dirt and debris out of the engine for cleaner combustion and longer engine life.

Fitment & Compatibility

• Engine check first: Confirm your mower uses a 140cc OHV engine (model numbers listed above). This filter will not fit smaller or larger engines without verifying dimensions.
• OEM cross-reference: Replaces OEM part numbers 951-14628 and 751-14628. If your current filter has a different number, measure it.
• Physical dimensions: The filter is paper, approximately 3.5” x 3.5” x 1.5”. Compare to your old filter (height, width, thickness) before buying.
• Brand fit: Works with MTD, Cub Cadet, Troy-Bilt, Yard Machines, and some Craftsman models using the same engine series. Check your mower’s model/engine plate for confirmation.

Key Things to Know

• Paper vs. foam: This is a dry paper filter—do not oil it. Foam filters require oil; paper filters do not.
• Install difficulty: Very easy. Remove the air filter cover (usually one screw or clip), swap the old filter, and reinstall. No tools beyond a screwdriver needed.
• Common gotcha: Some mowers use a different filter shape (e.g., round or rectangular with a pre-cleaner). Verify your filter housing matches this square paper type.
• Quality note: Aftermarket brand, not OEM. Users report it fits well and filters adequately, but may not last as long as OEM in dusty conditions.

Should You Buy It

Yes, if you have a 140cc OHV MTD/Troy-Bilt/Cub Cadet mower and want a cheap, easy-to-install replacement for basic maintenance. Avoid if your engine is a different series or you need a foam or oiled filter. For the price, it’s a solid budget option.
