*FCd (Full Contour design) is the innovative design by DNA®, that allows the filtering material to follow precisely the contour of the air box and uses the complete air box surface as “active filtering area“ eliminating “dead spots” that cause turbulence, increasing air flow and filtering efficiency
**Filtering efficiency is the amount of “dirt” the filter can maintain (stop) and protect the engine efficiently. For example the DNA® Filter for every 100 grams of dirt that it will receive, it will hold 98-99 grams, this applies even to fine dirt as small as 5 microns
