Twin Air Luchtfilter Yamaha YZ 125 87-88 & YZ 250 87 & YZ 490 87-90

The original formula that set the standard of excellence in air filter oils.
Many filter oils have a tendency to drain to one side, leaving part of your filter unprotected.
Blue ORIGINAL Liquid Power starts thin for deep penetration, then dries evenly to microcoat the foam cell walls with a shield that repels dirt while accelerating airflow.
