What It Is

This tune-up kit bundles an air filter, oil filter, and spark plug for Husqvarna riding mowers and zero-turns with Briggs & Stratton 17.5–21hp single-cylinder engines. It’s designed for routine maintenance to keep the engine running clean and starting reliably.

Fitment & Compatibility

• Models confirmed: YTH22V46, YTH2348, YTH24V48, Z246, YTH18542, Z254, YTA24V48, YTA18542, YTH24V54, YTA22V46.
• Engine types: Only for Briggs & Stratton single-cylinder engines in those HP ranges (17.5, 19.5, 20, 21). Will not fit Kawasaki, Kohler, or twin-cylinder engines.
• Check before buying:
  • Verify your mower’s engine model number (stamped on valve cover or blower housing).
  • Compare the spark plug gap (usually 0.030” for these engines) – the included plug may need gapping.
  • Oil filter thread size is standard 3/4” for most B&S singles.
• OEM cross-reference: Air filter 5041H, oil filter 492932S, spark plug 796112S (or equivalent). Aftermarket, but direct fit.

Key Things to Know

• Quality: Components are solid for the price – air filter is pleated paper, oil filter has anti-drain back valve. Not OEM, but reliable for seasonal use.
• Installation: Easy – no special tools beyond a spark plug socket and oil filter wrench. Change oil filter and air filter annually; spark plug every 100 hours.
• Common gotchas:
  • The spark plug may arrive pre-gapped at 0.030”, but always check with a feeler gauge.
  • The air filter is foam pre-cleaner style – do not oil it unless specified; it’s dry.
  • Oil filter can be tight – use a strap wrench to avoid stripping.
• Value: Cheaper than buying individually. Saves about $5–8 vs. separate OEM parts.

Should You Buy It

Buy this if you own one of the listed Husqvarna models with a Briggs & Stratton single-cylinder engine and want a simple, cost-effective tune-up kit for basic maintenance. Not for twin-cylinder or non-Briggs engines, or if you need OEM-only parts for warranty.
