NIMTEK FR691V Tune up Kits 11013-0752 Air Filter for Kawasaki FR691V FR730V FR651V FS481V FS541V FS600V FS651V FS691V FS730V 4-Stroke Engine Lawn Mower

What It Is

This NIMTEK tune-up kit provides the essential air filter, spark plug, and fuel filter replacements for a scheduled maintenance service on Kawasaki FR and FS series V-twin engines, commonly found on zero-turn mowers, garden tractors, and commercial walk-behinds.

Fitment & Compatibility

Before buying, confirm your engine model is one of these: FR691V, FR730V, FR651V, FS481V, FS541V, FS600V, FS651V, FS691V, or FS730V. The engine model number is stamped on the valve cover or blower housing. This kit replaces OEM part 11013-0752 (air filter) and works with compatible spark plug (typically NGK BPR4ES or similar) and fuel filter. It does not include oil or oil filter. Universal fit for any brand mower—Gravely, John Deere, Exmark, Toro, etc.—as long as the engine matches. The air filter measures approximately 6.75 x 4.5 x 2 inches; measure your existing filter to double-check.

Key Things to Know

• Quality vs OEM: NIMTEK is an aftermarket brand. Users report good fit and filtration, but it may not match OEM Kawasaki in lifespan. Fine for regular home use; consider OEM for commercial/heavy-duty.
• Installation difficulty: Easy—requires basic hand tools (socket wrench, screwdriver). No special skills needed. Swap the spark plug, air filter, and fuel filter (if included). Turn off fuel before replacing the fuel filter.
• Common gotcha: The kit may include a fuel filter that differs slightly in shape or barb size from your original. Check alignment and hose clamp fit before finalizing. If it doesn’t match, reuse your old fuel filter separately.
• Not a full tune-up: This kit covers air, spark, and fuel—but not oil, oil filter, or blade sharpening. Plan those separately.

Should You Buy It

If you own a Kawasaki FR/FS-powered mower and need a budget-friendly, all-in-one maintenance kit for seasonal tune-ups, this is a solid choice. It’s ideal for homeowners who want to save over buying OEM parts individually and don’t mind aftermarket quality. For commercial operators or those wanting exact OEM durability, stick with genuine Kawasaki.
