TWIN AIR Pre-Oiled Air Filter - Manufacturer Ref. 158383X

Designed for motocross use, this pre-oiled TWIN AIR filter combines patented design and meticulous manufacturing to provide filtration suited for dusty conditions. Ideal for riders who want to protect the airbox and engine while maintaining optimal airflow on trails and in competition.

• Double-layer foam: a first airy layer captures dust, sand, and coarse impurities; a second denser layer retains fine particles while facilitating airflow.
• Factory pre-oiled: ready to install, it optimizes particle adhesion to the foam without the need for additional oil during installation.
• Specific adhesive: the adhesive developed for TWIN AIR ensures the cohesion of the layers and resists solvents and gasoline.
• Compact size: slightly smaller than the original element to free up volume in the airbox and promote airflow circulation.
• Breathable seal and internal bonding: maximum contact surface with the housing body and elimination of gaps to prevent dust accumulation between layers.
