YTH22V46 YTH24V48 Air Filter Oil Filter Tune Up Kit for Husqvarna YTH22V46 YTH24V54 YTA22V46 YTA24V48 Poulan Pro PP20VA46 PB185A42 46'' 48'' Mower w/ 17.5hp 19.5hp 20hp 21hp Engine

What It Is

This tune-up kit bundles an air filter, oil filter, and spark plug for Husqvarna, Poulan Pro, and compatible 46–48-inch lawn tractors with 17.5–21 hp single-cylinder engines (typically Briggs & Stratton). It’s designed for routine seasonal maintenance to keep the engine running clean and starting reliably.

Fitment & Compatibility

Check your engine brand and model number – this kit fits Briggs & Stratton engines commonly used on these tractors, not Kohler or Kawasaki. Verify your mower’s model (e.g., YTH22V46, YTH24V54, YTA22V46, YTA24V48, Poulan Pro PP20VA46, PB185A42) and deck size (46” or 48”). The air filter is a pre-oiled foam type; measure your existing filter housing to confirm it matches. The oil filter is a standard spin-on type (OEM 492932S or equivalent). The spark plug is a Champion RC12YC (or compatible) – gap it to 0.030” before installing. If your engine uses a different plug or filter thread, this kit won’t work.

Key Things to Know

• Quality is solid for the price – aftermarket filters and plug work as well as OEM for normal use, but the foam air filter may need light re-oiling if it feels dry.
• Installation is straightforward – no special tools beyond a spark plug wrench and oil filter wrench. Expect 20–30 minutes total.
• Common gotcha – the spark plug may come pre-gapped, but always check and adjust to 0.030” to avoid misfires.
• Not for zero-turn or hydrostatic transmissions – this kit is strictly for the engine, not transmission filters.

Should You Buy It

Yes, if you own one of the listed Husqvarna or Poulan Pro tractors with a Briggs engine and want a cheap, reliable tune-up kit for annual service. It’s ideal for DIYers who prefer a single purchase over sourcing three parts separately. Skip it if you need OEM-branded parts for warranty or have a different engine brand.
