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. Industry Exclusive 150,000 Mile Maintenance Free PowerCore Filter
