What It Is

This is the OEM Honda air filter cover (part #17231-Z0L-0500) for GC135, GCV135, GCV160, and GCV190 series engines. It seals the air filter element inside the housing, preventing debris from entering the carburetor and engine.

Fitment & Compatibility

Engine models it fits: GC135, GCV135, GCV160 (including A, A0, LA, LA0, LA1, LE variants), GCV190A, GCV190LA.
What to check before buying:

• Engine model number – stamped on a metal tag near the spark plug or on the valve cover. This part is not universal; verify your engine is one of the listed series.
• Deck size irrelevant – this is an engine component, not a deck part.
• OEM vs aftermarket – this is genuine Honda OEM, so fit and seal are guaranteed. Aftermarket covers may warp or fit loosely.
• Measurements – roughly 4.5” x 3.5” x 1.5”. If your current cover is cracked or missing, this is the direct replacement.
• Also check the foam pre-filter (if your engine has one) – not included, but often needs replacing at the same time.

Key Things to Know

• Quality – Thick, molded plastic with a tight rubber gasket. Holds up to heat and vibration better than cheap knockoffs.
• Installation – Easy. Remove the old cover (one or two screws), swap the air filter element if dirty, then snap on the new cover and tighten screws. No tools beyond a screwdriver needed.
• Common gotcha – The cover’s retaining tabs are fragile; don’t overtighten screws or force it. If the gasket is misaligned, air leaks can cause rough running.
• When to replace – If the cover is cracked, the gasket is torn, or the retaining clips are broken. A damaged cover lets unfiltered air into the engine, accelerating wear.

Should You Buy It

Yes, if your Honda GC/GCV series engine has a damaged or missing air filter cover. The OEM fit is exact, the price is fair for a genuine part, and it’s a quick, simple fix that protects your engine from debris. For any other engine model, look up your specific part number.
