YAMAKATO GX160 GX200 Air Filter Assembly with Housing Cover

YAMAKATO's air filter assembly with housing cover and extra AF ZE18 element replaces common GX120/GX160/GX200 filter parts to restore proper engine airflow and protect your small engine.

When maintaining small engines—pressure washers, generators, tillers and walk-behind equipment—clean, well-sealed air filtration matters. This replacement assembly is designed to match the fit and function of original Honda-style intake housings and filter elements, offering a ready-to-install housing, gasket and an additional AF ZE18 element so you can service the engine quickly and reliably without hunting down multiple parts.

What comes in the package and how easy is installation?

The kit includes the air filter housing cover, the air filter assembly gasket and an extra AF ZE18 filter element, so you receive both sealing hardware and a replacement element in one purchase. Installation is straightforward for anyone comfortable removing the old housing: unbolt the cover, swap the gasket and element, then reinstall using the existing mounting points.

• Complete housing cover sized for GX120/GX160/GX200 intake locations.
• Included gasket ensures a tight seal to reduce unfiltered air ingress.
• AF ZE18 extra element fits common replacement part references for quick changeouts.

How does this part improve engine performance and longevity?

A properly sealed and fitted air filter assembly prevents dirt and debris from entering the carburetor and combustion chamber, which helps maintain fuel-air balance and reduces wear. Using a correctly sized OEM-style element and housing restores the intended airflow characteristics for stable idle and power delivery.

• Seals with a replacement gasket to limit unfiltered air entry.
• Element captures dust and particles for cleaner intake air.
• Restores original airflow path to support consistent engine response.

Are there any limitations or things to check before ordering?

Note that this assembly does not include a fuel tank breather; verify your machine’s breather location before purchase. Always compare the images and part numbers on your existing air box to confirm fit, and keep the OEM mounting hardware for reinstallation unless replacements are needed.

• Does not include fuel tank breather—confirm your model’s parts list.
• Check compatibility with listed replacement references (e.g., Stens 100-784, Oregon 30-404).
• Gasket and spare filter element included, but use original bolts if in good condition.

This YAMAKATO air filter assembly is suited for DIY mechanics, small engine service shops and equipment owners who need a cost-effective OEM-style replacement. If you maintain pressure washers, portable generators, lawn and garden equipment or compact utility engines that use Honda GX120/GX160/GX200-style intake parts, this kit gives you both the housing and an extra element to complete a fast service. Choose this assembly when you want an exact-fit cover, a new sealing gasket, and a backup AF ZE18 filter element to minimize downtime during routine maintenance.
