TL43/CG430/40-5/TL52/CG520/44-5 Brush Cutter Air Filter Iron Gasket + Air Filter Foam
Complete Air Intake Service Kit for 43–52cc Brushcutters
This air filter service kit is a direct replacement for the air intake system on TL43, CG430, 40-5, TL52, CG520, 44-5, and compatible 43–52cc brushcutters. The kit typically includes the iron gasket (gasket plate) and the foam air filter element, providing a comprehensive solution for restoring proper engine breathing and protection.
The foam air filter traps dust and debris before they enter the carburetor and cylinder, preventing premature wear and maintaining engine performance. The iron gasket ensures an airtight seal between the carburetor and the air filter housing, preventing unfiltered air from bypassing the filter and entering the engine.

FAQ
Q: How do I confirm this air filter kit fits my brushcutter?
A:Check your machine model number on the identification plate. This kit is compatible with TL43, CG430, 40-5, TL52, CG520, 44-5, BC430, BC520, and compatible 43–52cc brushcutters.
Q: Can the foam air filter be cleaned and reused?
A: Yes, foam air filters are washable and reusable. Clean the filter in warm soapy water, rinse thoroughly, and allow it to dry completely before reinstalling. Lightly oil the foam before installation to improve dust trapping efficiency. Replace the filter if it shows signs of deterioration or damage.
Q: What are the symptoms that indicate the air filter needs replacing?
A: Common symptoms include hard starting, loss of power, poor acceleration, increased fuel consumption, or the engine running rough. If the filter is visibly dirty or damaged, it should be replaced immediately. A clogged filter restricts airflow, causing the engine to run rich and lose performance.
