NIMTEK 11013-0752 FR691V Air Filter with 11013-7046 Pre Filter for Kawasaki FR651V FR691V FR730V FS481V FS541V FS651V FS691V FS730V 4-Stroke Engine Lawn Mower

What It Is

This is a replacement air filter set for Kawasaki FR and FS series V-twin engines (FR651V, FR691V, FR730V, FS481V, FS541V, FS651V, FS691V, FS730V) used in commercial and residential zero-turn mowers, lawn tractors, and walk-behinds. Includes a primary foam filter (11013-7046) and a secondary paper filter (11013-0752) to protect the engine from debris.

Fitment & Compatibility

• Engine models only: Works exclusively on Kawasaki FR/FS series 4-stroke V-twins listed above. Not for Kohler, Briggs & Stratton, or Honda engines.
• OEM cross-reference: Replaces Kawasaki OEM parts 11013-0752 (paper) and 11013-7046 (foam). Check your engine’s air filter housing for these numbers.
• Physical check: Measure the filter housing opening (approx. 5.5" x 4.5" for the paper filter). If your current filter is significantly larger or smaller, this set won’t fit.
• Mower brand doesn’t matter: Fits any mower (John Deere, Husqvarna, Toro, Gravely, etc.) that uses one of the listed Kawasaki engines. Verify your engine model number (stamped on the valve cover).

Key Things to Know

• Installation is tool-free: Remove the cover, swap the foam and paper filters, and reattach. Takes under 5 minutes.
• Foam pre-filter must be oiled: The foam filter comes dry—apply a light coat of air filter oil (or engine oil) before installing to trap fine dust. Running it dry reduces filtration.
• Quality is solid for the price: Users report good fitment and construction compared to OEM, but the foam may be slightly less dense. Fine for residential use; commercial operators may prefer OEM for longer intervals.
• Common gotcha: Don’t over-oil the foam—excess oil can drip into the carburetor. Squeeze out any pooling oil after application.

Should You Buy It

If you own a Kawasaki FR/FS engine and want an affordable, direct-replacement air filter set that’s easy to install, this is a good value. It’s ideal for home users and light commercial use who change filters seasonally. For heavy-duty, all-day commercial mowing, OEM may offer slightly longer service life, but for $7.99, this set performs well for most applications.
