Replacement air filter 10-pack

This pack supplies ten replacement air filters for Stihl petrol-powered trimmers and hedge cutters. It fits the FC55, FS38, FS45, FS46, FS55 and HL45 models. Each filter matches OEM reference 4140 124 2800. The set is intended for routine maintenance on two-stroke single-cylinder engines.

Tool-free swap in minutes

The filter housing on these machines opens without tools, so the old element lifts out and the new one seats in seconds. The most common issue is forgetting to wipe the sealing surface before fitting the fresh filter, which can let unfiltered air into the carburettor. A quick brush of the housing prevents that problem.

Verify model and OEM number first

Check the model plate on your machine to confirm it is one of the listed types before ordering. Cross-reference the OEM number 4140 124 2800 with your parts manual to ensure exact compatibility. This pack does not suit models outside the stated range.
