Kyosho 74031-13-1B Replacement Air Cleaner Sponge Set (2pcs)  [KY-74031-13-1B]

Air Filtration Optimised for Kyosho Engines

Keep your Kyosho KE21SP and KE25SP engines running clean with the Kyosho 74031-13-1B Air Cleaner Sponge. This two piece pack gives you a direct replacement plus a spare for routine maintenance to help preserve engine reliability.

Engine Compatibility and Fit

The sponges are made to fit the KE21SP and KE25SP intake assembly, providing proper filtration without modifying the airbox. Regularly replacing a clogged sponge prevents grit and dust from accelerating wear inside the engine.

Quick Replacement Guide

Changing the sponge is straightforward: remove the air cleaner cover, take out the old foam and seat the new sponge correctly before refitting. Check the sponge after several runs and swap it when it becomes compressed or visibly dirty to maintain performance.
