Ultimate Racing UR0505 -  Air Filter Oil 60ml.

This is a 60ml bottle of Ultimate Racing Air Filter Oil. This specially-developed, high-quality external air filter oil is easily applied to the air filters of any nitro car. This air filter oil is sticky enough to stop dirt and dust, while still allowing airflow to ensure no loss of performance. It does not clog the small pores on the RC filters like some of the heavier motorcycle oils.
