YT3000 LT2000 Air Filter Oil Filter Tune Up Kit for Craftsman T2200 YS4500 YTS3000 T1400 42" 46" Lawn Tractor Riding Mower with 19.5hp 20hp 21hp Engine

What It Is

This is a tune-up kit for Craftsman lawn tractors, containing an air filter, oil filter, and spark plug. It’s designed for routine maintenance on 19.5hp to 21hp engines used in models like the T2200, YS4500, YTS3000, T1400, and others with 42" or 46" decks.

Fitment & Compatibility

Before buying, verify your engine’s horsepower (19.5–21hp) and model number—this kit fits Craftsman/MTD tractors with single-cylinder OHV engines, not twin-cylinder or Kohler/John Deere models. Check your air filter part number (usually 725-04078 or 725-04078A) and oil filter (e.g., 492932S). Measure the spark plug gap before installing; it should match your engine’s spec (typically 0.030"). If you have a different deck size or engine brand, this kit likely won’t work.

Key Things to Know

• Installation is easy—swap the air filter (no tools), oil filter (hand-tighten), and spark plug (use a socket wrench). Takes about 20 minutes.
• Quality is decent for the price—filters are aftermarket, not OEM, but rated well. Some users report the spark plug may be pre-gapped incorrectly; always check with a feeler gauge.
• Common gotcha—the oil filter may be slightly smaller than OEM. This is fine, but ensure it seals snugly. Also, confirm your engine uses a single spark plug (most do; twin-cylinder engines require two).
• Missing drain pan—you’ll need your own oil and a pan for the oil change; the kit only includes filters and plug.

Should You Buy It

Buy this if you own a compatible Craftsman tractor (T2200, YS4500, etc.) and want a cheap, quick tune-up without hunting for individual parts. It’s ideal for DIYers comfortable with basic engine maintenance. Skip it if you need OEM components or have a different engine brand.
