17231-Z0L-050 Air Filter Cover for Honda GCV160 GC135 GC160 GC190A GCV135 GCV160A GCV160LA Engine HRB216 HRR216 HRS216 HRT216 HRZ216 Lawn Mower

What It Is

This is the OEM plastic air filter cover (part 17231-Z0L-050) for Honda GCV160, GC135, GC160, GC190A, GCV135, GCV160A, GCV160LA engines, and the HRB216, HRR216, HRS216, HRT216, HRZ216 lawn mower models. It seals the air filter element inside the housing, keeping debris and moisture out of the carburetor.

Fitment & Compatibility

• Engine check: Only fits Honda GCV160, GC135, GC160, GC190A, GCV135, GCV160A, GCV160LA engines. Not compatible with GCV190, GCV200, or GX series.
• Mower models: Works on HRB216, HRR216, HRS216, HRT216, HRZ216 – verify your mower’s model number on the sticker under the seat or on the engine shroud.
• OEM vs aftermarket: This is genuine Honda; aftermarket covers may fit but often use softer plastic that warps or cracks faster.
• Measurement check: The cover is roughly 4.5” x 3.5” x 1.5”. Measure your old cover’s mounting tabs and screw hole spacing (about 3.5” center-to-center) to confirm match.

Key Things to Know

• Installation: Tool-free – just unsnap the clips or remove one Phillips screw (depending on your engine variant) and swap. Takes under 2 minutes.
• Common gotcha: The cover clips are brittle. If yours is cracked, replace it immediately to avoid dirt entering the carb. Do not over-tighten the screw – it can crack the cover.
• Quality: OEM Honda plastic is thicker and UV-resistant compared to many third-party covers. Expect it to last 3-5 years under normal use.
• Warning: If your old cover is missing, check the air filter element for damage or dirt before installing the new cover.

Should You Buy It

Buy this if your Honda GCV160 or compatible mower’s air filter cover is cracked, missing, or won’t seal properly. It’s a cheap, fast fix that prevents engine damage from unfiltered air. If you need a cover for a different engine series (like GXV or GCV190), look elsewhere. For $8.49, this OEM part is the right choice for reliability.
