Honda Genuine OEM HRX217 (HRX2174HYA) (HRX2174HZA) (HRX2174VKA) (HRX2174VLA) Walk-Behind Lawn Mower Engines AIR Filter Cleaner Element (Engine Serial Numbers GJAAA-2851077 and up)

What It Is

This is the OEM air filter element for Honda HRX217 walk-behind mowers, specifically for engines with serial numbers GJAAA-2851077 and up. It traps dirt and debris before they enter the carburetor, ensuring clean combustion and engine longevity.

Fitment & Compatibility

Check your mower’s engine serial number—this filter fits HRX2174HYA, HRX2174HZA, HRX2174VKA, and HRX2174VLA models only if the engine number is GJAAA-2851077 or higher (located on the engine shroud or near the spark plug). It’s a direct OEM replacement; no adapter or modification needed. Deck size (21”) is consistent across these models, but do not assume compatibility with other HRX217 variants with lower serial numbers. Aftermarket filters may fit physically but lack the same filtration media density.

Key Things to Know

• OEM vs. aftermarket: This Honda part uses a specific foam-and-paper element that resists oil saturation better than generic copies. Cheap alternatives often clog faster or let fine dust through.
• Installation: Takes about 2 minutes—remove the cover, swap the old filter, and re-secure the cover. No tools required. Ensure the foam pre-filter is correctly positioned; misalignment can bypass dirt.
• Common gotcha: If your mower runs rough after replacement, double-check the filter is seated flat against the housing seal. A gap causes unmetered air and lean running.
• Maintenance interval: Replace every 100 hours or annually, whichever comes first. In dusty conditions, inspect monthly and tap out loose debris.

Should You Buy It

Yes, if you own an eligible HRX217 and want zero fitment guesswork and maximum engine protection. The price is fair for OEM quality, and the high rating reflects reliable performance. Skip cheap aftermarket filters—they’re not worth the savings when a clogged element can damage the carburetor.
