Kawasaki Genuine 99969-6419 Tune Up Kit

What It Is

The Kawasaki Genuine 99969-6419 Tune Up Kit includes a spark plug, air filter, fuel filter, and oil additive—everything needed for a single annual maintenance service on Kawasaki small engines (found in many zero-turn mowers, walk-behinds, and generators).

Fitment & Compatibility

This kit fits Kawasaki FS, FX, FH, and FR series engines (e.g., FS481V, FX600V, FH580V, FR600V) from roughly 2005 onward. Before buying, confirm your engine model number (stamped on the valve cover or blower housing) and check that your engine uses a standard NGK BPR6ES spark plug (most do). It is not compatible with older FJ or FC series engines, or with Briggs & Stratton, Kohler, or Honda engines. No deck-size or mower-brand check needed—fitment is purely engine-series based.

Key Things to Buy

• Quality is OEM: All components are genuine Kawasaki, not aftermarket. The air filter is dense foam, the fuel filter is high-flow, and the spark plug is pre-gapped. Expect consistent performance.
• Installation is easy: Takes about 15-20 minutes. You’ll need a socket wrench (for the plug), pliers (for fuel line clamps), and a flathead screwdriver (for the air filter cover). No special tools.
• Common gotcha: The kit does not include engine oil—you’ll need SAE 10W-30 or 10W-40 (check your manual). Also, the fuel filter is universal-style, so you may need to trim the hose slightly if your lines are short.
• Price: At $73.49, it’s pricier than aftermarket kits (often $25–$40), but the OEM parts last longer and won’t void your warranty.

Should You Buy It

Buy this kit if you own a Kawasaki-powered mower and want a single, hassle-free package for annual maintenance—especially if you value OEM reliability over saving a few bucks. Skip it if you’re on a tight budget or have an older engine that doesn’t match the series list; aftermarket alternatives with similar parts cost less.
