The Kyosho 92023-1B Air Cleaner Sponge set supplies three replacement foams for common RC air filter assemblies. These sponges act as a first line of defence against dust and airborne particles entering the engine.
Manufactured to suit standard filter cups, the foams aim to combine effective dust capture with minimal airflow restriction. Regular changes keep the intake clean and help maintain steady running.
Check the sponge after running on dusty or muddy surfaces and replace when contamination is visible. Carrying spares makes field servicing straightforward and reduces the risk of engine damage from dirty air.
