The Mower Shop Tune-Up Kit for HRX217 (K4-K6) and HRR216 (K9-K11) Lawnmowers

What It Is

The Mower Shop Tune-Up Kit provides the essential replacement parts—air filter, fuel filter, spark plug, and oil—for a complete annual service on Honda HRX217 (K4-K6) and HRR216 (K9-K11) mowers. Designed for DIY maintenance, it keeps your mower running cleanly and starting reliably.

Fitment & Compatibility

This kit fits only Honda HRX217 models with engine code K4, K5, or K6, and HRR216 models with code K9, K10, or K11. The engine code is stamped on the blower housing or near the spark plug—check this before buying. It works with 20-inch and 21-inch deck sizes on these specific models. All parts are aftermarket but match OEM specifications; no modifications or extra adapters are needed. Does NOT fit older HRX217 (K1-K3) or HRR216 (K1-K8) models.

Key Things to Know

• Quality is solid for the price – Parts are well-made and fit snugly, but the fuel filter is slightly smaller than OEM. Still functional.
• Easy install – Basic hand tools only (socket wrench, pliers). Oil is included, but you’ll need to dispose of the old oil properly.
• Check your mower’s oil type – Kit includes SAE 30 (for warm weather). If you mow in cool conditions (<40°F), buy 10W-30 separately.
• Common gotcha – The spark plug gap is pre-set, but verify it with a gap tool (0.028-0.031 in.) before installing. Also, the air filter foam pre-oiling is recommended but not included—use a few drops of engine oil.

Should You Buy It

If you own a compatible Honda HRX217 or HRR216 and want a single, affordable kit for annual maintenance instead of sourcing each part separately, this is a solid choice. It’s ideal for DIYers who value convenience and decent quality over OEM-branded parts. Skip it if you prefer genuine Honda parts or need a kit for a different engine series.
