Kyosho 74031-13-1B Air Cleaner Sponge Set 2pcs Classic Fit  [KY-74031-13-1B]

Protect Your Kyosho Engine

For owners of KE21SP and KE25SP engines, the Kyosho 74031-13-1B Air Cleaner Sponge provides a direct foam replacement to keep debris out of the intake. The pack contains two sponges so you can rotate or replace as part of scheduled upkeep.

Compatibility Details

Engineered for the KE21SP and KE25SP, these sponges align with the stock air cleaner housing to maintain proper filtration flow. Replacing a blocked sponge reduces the chance of abrasive particles damaging moving parts.

How to Replace the Sponge

Remove the air cleaner cover, take out the old foam and insert the new sponge ensuring it sits evenly. Regular checks after dusty running sessions will help you decide when to swap to the spare piece.
