Volant air intake systems utilize a high-velocity venturi filter adapter which provides a smooth transition through the MAF sensor into the intake tube for a much needed airflow improvement over the factory rubber tubing and resonator box. Volant's Cold Air box is larger than the factory unit and incorporates a larger opening to collect a higher volume of colder ambient air. This model includes a no maintenance PowerCore® filter. By using Donaldsons PowerCore Filtration technology submicron contaminants load on the surface rather than collecting in the depth of the filter. This is why we warranty our replacement air filters for 4 years or 150000 miles in urban conditions whichever comes first.
