Air Filter Spark Plug 17211-ZL8-023 17231-Z0L-050 for Honda GCV135 GCV160 GCV190 Engine HRB216 HRB217 HRR216 HRS216 HRT216 HRX217

What It Is

This is a combo kit containing both an air filter (17211-ZL8-023) and a spark plug (17231-Z0L-050) designed for Honda GCV135, GCV160, and GCV190 engines. It’s a direct replacement for routine maintenance on Honda walk-behind mowers like the HRB216, HRB217, HRR216, HRS216, HRT216, and HRX217.

Fitment & Compatibility

• Engine check: Confirm your mower has a Honda GCV135, GCV160, or GCV190 engine (stamped on the engine shroud or valve cover).
• Model check: Works with HRB216, HRB217, HRR216, HRS216, HRT216, and HRX217 series mowers, but only if they use these specific engine models.
• OEM vs aftermarket: This is genuine Honda OEM, not a third-party knockoff. Aftermarket filters may differ in foam density or paper media; spark plugs often lack proper gap or heat range.
• Measurements: Air filter dimensions are roughly 4.5” x 3” x 1.5” (pre-formed foam and paper element). Spark plug is a standard 14mm thread, 19mm hex, with a 0.028–0.031” gap (pre-gapped, but always verify).
• What to avoid: Do not use on older Honda engines (e.g., GXV120, GXV160) – mounting holes and plug threads differ.

Key Things to Know

• Quality: OEM Honda parts ensure correct fit and filtration; cheap aftermarket filters can allow debris into the carburetor.
• Installation difficulty: Very easy – no special tools beyond a socket wrench for the spark plug. Air filter snaps in without screws.
• Common gotcha: The spark plug comes pre-gapped, but always double-check with a feeler gauge. A too-tight gap can cause misfire; too-wide can cause hard starting.
• Maintenance interval: Replace air filter every 100 hours or annually; spark plug every 200 hours or if you notice rough idle or hard starting.

Should You Buy It

Yes – if you own a Honda GCV135/160/190 mower and want a hassle-free, OEM-quality tune-up. It’s a great value at $8.99 for both parts, saves you from buying separately, and eliminates compatibility guesswork. Ideal for DIY homeowners who want reliable performance without overpaying at a dealer.
