What It Is

This is the OEM Honda carburetor air filter for the GCV160 engine, commonly used on Honda HRX, HRR, and HRS series walk-behind mowers, as well as some pressure washers and generators. It traps dirt and debris before air enters the carburetor, ensuring clean combustion and preventing engine wear.

Fitment & Compatibility

• Engine: Honda GCV160 (check your engine model number stamped on the valve cover or blower housing).
• OEM part numbers: 16100-Z0L-023, 16100-Z0L-853, 16100-ZMO-803, 16100-ZMO-804. All four are interchangeable.
• Mower models: HRX217, HRR216, HRS216, and others with the GCV160 engine. Also fits Honda Harmony, Versamow, and some self-propelled models.
• What to check: Remove your old filter and compare shape—this is a rectangular foam filter with a plastic frame. Measure width (approx. 3.5 inches) and height (approx. 2 inches). Aftermarket filters may differ slightly in foam density or fit, so stick with OEM for guaranteed seal.
• Not compatible with GCV190, GCV200, or GXV160 engines—those use different filter housings.

Key Things to Know

• Quality: OEM Honda filter uses dense, oil-resistant foam that holds up longer than cheap aftermarket alternatives. The plastic frame is durable and won’t crack during removal.
• Installation: Easy—remove the air filter cover (usually one or two screws), swap the old filter, and reinstall. No tools needed beyond a screwdriver. Ensure the foam is lightly oiled (use Honda foam filter oil or a light engine oil) for maximum dust capture.
• Maintenance interval: Replace every 100 hours or once per mowing season, whichever comes first. Check more often if mowing in dusty or dry conditions.
• Common gotcha: Don’t overtighten the cover screws—they can strip the plastic housing. Hand-tighten only.

Should You Buy It

Yes, if you own a Honda GCV160 mower and want a guaranteed fit with OEM quality. It’s a small price for reliable engine protection, and the high rating reflects consistent performance. Skip cheap knockoffs that may let dirt bypass the filter. If you have a different engine or an aftermarket carburetor, verify compatibility first.
