What It Is

This is an aftermarket air filter designed for Troy-Bilt push mowers (TB130, TB240, TB250, TB190, TB110) and Honda GCV120, GCV135, and GCV160 engines. It replaces OEM filters like 491588, 491588S, 399959, and AM116236.

Fitment & Compatibility

Before buying, confirm your mower’s engine is a Honda GCV120, GCV135, or GCV160—not a different brand or model. Check your current filter’s shape: this is a rectangular foam element with a plastic housing frame. Measure the filter slot (roughly 5.5” x 3.5”) and compare to your old one. It fits Troy-Bilt push mowers listed, but not self-propelled or riding models. If your mower uses a cylindrical or paper-only filter, this won’t work.

Key Things to Know

• Quality: Foam element is washable and reusable, but not as fine-filtering as OEM paper filters. Clean it with soapy water every 25 hours of use.
• Installation: Tool-free—remove the cover, swap the filter, and snap the cover back. Takes 2 minutes.
• Common gotcha: The foam may be slightly thicker than OEM; ensure the cover closes fully without bulging. If it doesn’t, trim the foam slightly with scissors.
• Price vs. OEM: At $7.99, it’s about half the cost of a genuine Honda filter, but may need more frequent cleaning.

Should You Buy It

Buy it if you have a Troy-Bilt push mower with a Honda GCV120-160 engine and want an affordable, washable alternative to OEM filters. It’s fine for light-duty mowing on clean lawns, but skip it if you mow dusty, sandy, or tall, dry grass—the foam lets more particles through than a paper filter.
