17211-ZL8-023 Air Filter & 17231-Z0L-050 Cleaner Cover for Honda GCV135 GCV160 GCV190 Engine HRB216 HRB217 HRR216 HRS216 HRT216 HRX217 Motor Lawn Mower with Fuel Filter Spark Plug Parts

What It Is

This is a three-piece maintenance kit for Honda GCV135, GCV160, and GCV190 engines, commonly found on HRB216, HRB217, HRR216, HRS216, HRT216, and HRX217 mowers. It includes the air filter (17211-ZL8-023), foam pre-filter cover (17231-Z0L-050), plus a fuel filter and spark plug for a complete tune-up.

Fitment & Compatibility

• Engine check first: Verify your mower has a GCV135, GCV160, or GCV190 engine (look for a sticker near the spark plug or under the air filter cover). This kit will not fit Honda GXV, GX, or other engine series.
• Model compatibility: Works with HRB216, HRB217, HRR216, HRS216, HRT216, and HRX217, but only if they use the listed engines. Deck size (e.g., 21-inch) does not matter—engine model is the only fitment factor.
• OEM vs aftermarket: This is genuine Honda OEM, so fitment is exact. Aftermarket copies often use cheaper foam that degrades faster or have non-matching spark plug gaps.
• Measurements: Air filter is roughly 4.5” x 2.5” x 1.2”. Foam cover is about 3.5” x 2.5”. Spark plug is standard 14mm thread, 0.028-0.031” gap (pre-gapped, but verify).

Key Things to Know

• Installation difficulty: Easy—no tools needed for the air filter and foam cover; spark plug requires a 5/8” socket. Fuel filter swap may need pliers for hose clamps.
• Common gotcha: The foam pre-filter must be oiled lightly with engine oil before installation (squeeze out excess). Running it dry will let fine dust through.
• Quality: Genuine Honda paper and foam elements last 100+ hours or two seasons; cheap knockoffs often fail in one. Spark plug is NGK or equivalent—reliable.
• Replacement interval: Change air filter and foam cover every 50 hours or yearly. Fuel filter every 100 hours. Spark plug every 100 hours or if hard starting.

Should You Buy It

This kit is a solid value for anyone with a compatible Honda GCV engine who wants a one-stop, OEM-quality tune-up. It’s ideal for DIY homeowners who mow regularly and prefer exact fitment over saving a few bucks on generic parts. If your engine is a different series (e.g., GXV) or you need only one component, skip it and buy individual parts instead.
