GCV160 Air Filter + Pre Filter, Compatible with Honda Engine GC160 GC190 GCV190 GX100 17211-zl8-023, Replace Lawn Mower Flat OEM Air Cleaner

What It Is

This is a replacement air filter set (main filter + pre-filter foam) designed for Honda GCV160, GC160, GC190, GCV190, and GX100 engines. It traps dirt and debris before they enter the carburetor, protecting engine life on walk-behind mowers, pressure washers, generators, and other small equipment using these Honda engines.

Fitment & Compatibility

Before buying, check the engine model number stamped on the valve cover or shroud—not the equipment brand. This filter fits Honda engines with OEM part number 17211-ZL8-023, which is a flat, rectangular panel filter. It is not compatible with round or cylindrical air filter housings. Measure your existing filter: this one is roughly 5.5 x 3.5 x 1.5 inches. It replaces OEM Honda filters and many aftermarket equivalents. Does not fit Honda GX160, GX200, or GCV200 engines (those use different filter shapes).

Key Things to Know

• Two-piece design: The foam pre-filter (yellow) catches larger particles; the paper main filter (white) catches fine dust. Both must be installed together for proper sealing.
• Installation is easy: No tools needed—remove the air filter cover, swap the old filter set, and reattach the cover. Takes under 2 minutes.
• Common gotcha: The pre-filter foam must be lightly oiled (use foam filter oil, not engine oil) to trap dust effectively. Running it dry reduces filtration.
• Quality note: This is an authentic Honda part, not a generic. Fit and sealing are exact—no gaps that let unfiltered air bypass the filter.

Should You Buy It

If you own a Honda GCV160, GC160, GC190, GCV190, or GX100 engine and need a reliable, OEM-quality replacement at a low price, this is a solid buy. It’s especially worthwhile for mowers used in dusty conditions where the pre-filter adds extra engine protection. Avoid cheap generics that may not seal properly.
