Self-estinguishable air filters, entirely hand-made in Italy by Marchald Filters, a company with more than 40 years of experience.
The continuous development of the product in any kind of discipline allowed Marchald Filters to create a new dual-layer foam filter that increases the protection of the engine, thanks to the increased thickness (+25%) and the particular porosity of the foam.
This filter slightly decrease the engine performance but it is hihly recommended in extreme dusty conditions and/or when it is not possible to often replace the air filter like in enduro, endurance and rally races.
