GCV170 GCV190 Air Filter Cover for Honda GCV 170 HRN216 GCV200 HRX217-K6 Lawn Mower GCV170LA GCV200LA G5B G5BR S3C S3L Engines Tune up Kit 17231-Z9L-000

What It Is

This is an OEM Honda air filter cover (part #17231-Z9L-000) designed for GCV170 and GCV190 engines, commonly found on Honda HRN216, HRX217-K6, and select walk-behind mowers. It seals the air filter element inside the housing to prevent debris from entering the carburetor.

Fitment & Compatibility

Before buying, confirm your engine model—this cover fits GCV170, GCV190, GCV200, GCV170LA, GCV200LA, and the G5B, G5BR, S3C, S3L engine variants. It is not compatible with GCV160 or GCV200 engines with a different housing design. Check your mower’s model plate (under the rear flap or near the engine) for the exact engine code. Measure the existing cover’s width (approx. 3.5 inches) and tab alignment—this cover uses a single center tab with two side clips. OEM part, so no aftermarket fitment guesswork.

Key Things to Know

• Quality: Genuine Honda plastic—more durable than most aftermarket covers, less likely to warp from heat or UV exposure.
• Installation: Tool-free; simply unclip the old cover, remove the filter, and snap the new one on. Takes under 2 minutes.
• Common gotcha: The cover is often sold as a “tune-up kit” but may not include the filter itself. Verify you’re buying just the cover or a full kit if you need both.
• Check the gasket: If your old cover’s foam seal is worn, this replacement includes a new seal—don’t reuse the old one.

Should You Buy It

If you own a Honda GCV170/190/200 mower and your air filter cover is cracked, missing, or won’t seal properly, this OEM part is a no-brainer. It’s cheap, easy to install, and restores proper filtration. Skip it if your cover is intact—just clean the filter.
