Jitsie - Montesa 4RT Airfilter

Jitsie air filters feature high performance dual layer bonded foam for maximum power and protection featuring an exclusive extra wide foam-rubber base which guarantees a waterproof and airtight fitment. Constructed with larger than OEM surface area for maximum airflow, the course outer layer will catch large particles and resist clogging whereas the inner layer takes care of even the finest of dust.

All Jitsie air filters come pre-oiled and can be used directly after installation! Please note that the Jitsie air filter for the Montesa 4RT is designed to be used without the metal cage.
