Robitronic off road air filters
Robitronic have introduced a number of new off road air filters and accessories, starting with this universal dual-stage air filter set. Due to it dual-stage design, it keeps even the tiniest debris away from the engine and comes supplied with oil. There is also two new oval air filters that are supplied with rain covers. Designed to fit under even tight bodies there is a single and dual stage version and again both are supplied with oil. Finally there is the Dirtbag, which you put over the air filter, preventing it from contaminating early and uses a specially designed material that makes it almost impossible for dirt and debris to stick to its surface.
