Genuine Honda OEM Air Filter & Pre Filter 17211-ZG9-M00, 17218-ZG9-M00 for GXV140

What It Is

This is a two-piece air filter set (main filter 17211-ZG9-M00 and pre-filter 17218-ZG9-M00) designed for Honda GXV140 engines. It traps dirt and debris before they enter the carburetor, protecting engine life on push mowers, tillers, and pressure washers.

Fitment & Compatibility

• Exact engine match: Fits Honda GXV140 (check engine model number stamped on valve cover or near the dipstick).
• Common mower models: HRX217, HRR216, HRS216, and similar Honda walk-behind mowers with GXV140 power.
• Not for: GXV120, GXV160, or other Honda engine families—dimensions differ.
• OEM vs aftermarket: This is genuine Honda; aftermarket copies may not seal properly or fit the pre-filter notch. Measure the old filter’s length and width (approx. 4.5” x 3.5”) to confirm.
• Check before buying: Verify your engine’s model code (e.g., GXV140K1) and that your air box uses two separate filter elements (not a single foam/oil type).

Key Things to Know

• Quality: OEM foam pre-filter and paper main filter; the pre-filter extends service life of the main filter by trapping larger debris.
• Installation: No tools needed—remove air box cover, replace both filters, reattach cover. Takes 2 minutes.
• Common gotcha: Do not oil the paper main filter; only the pre-filter can be cleaned with mild soap and reused if not torn. Always replace both together.
• Service interval: Replace every 100 hours or annually, more often in dusty conditions.

Should You Buy It

If you own a Honda GXV140-powered mower and want reliable, no-guess fitment, this OEM set is the right call. It’s cheap, easy to swap, and avoids the uneven sealing or premature clogging you can get with generic filters.
