Z246 Air Filter Tune Up Kit For Husqvarna YTH26V54 YTH22V42LS 2348LS 2246LS Z4824 MZ61 Z246I RZ46I MZ6128 RZ4222F Mower Lawn Tractors

What It Is

This is a pre-packaged air filter and spark plug tune-up kit designed for Husqvarna Z200/Z400-series zero-turn mowers and select YTH lawn tractors. It includes the replacement air filter element, pre-filter, and spark plug needed for routine annual maintenance.

Fitment & Compatibility

Before buying, confirm your model and engine type. This kit fits specific Husqvarna mowers including Z246, Z4824, MZ61, Z246I, RZ46I, MZ6128, RZ4222F, YTH26V54, YTH22V42LS, 2348LS, and 2246LS. It is not universal—verify your engine’s air filter housing shape and spark plug gap (typically 0.030″ for this plug). Measure your existing filter’s length and width; the included filter is roughly 6″ x 4″. If your mower uses a different engine (e.g., Kawasaki or Briggs & Stratton), this kit likely won’t fit. OEM part cross-reference: air filter 532192065, spark plug RC12YC.

Key Things to Know

• Quality concerns: The 3.7 rating reflects some users reporting the aftermarket filter is less dense than OEM, which may reduce filtration on dusty properties.
• Installation difficulty: Easy—10 minutes with a socket wrench and screwdriver. Remove the air filter cover, swap the filter and pre-filter, then replace the spark plug (gap it first).
• Common gotcha: The spark plug may not match your engine’s heat range. If your mower runs hot or under heavy load, stick with the OEM plug (Champion RC12YC).
• Not a full tune-up: This kit covers air and spark only. You’ll still need oil and fuel filter separately.

Should You Buy It

If you own one of the listed Husqvarna models and want a quick, affordable maintenance pack for light-to-moderate use, this kit works. For heavy-duty mowing or dusty conditions, pay a few dollars more for OEM filters. Skip it if your engine requires a different spark plug type or if you need a fuel filter included.
