• 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 Cool 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 two (2) Oiled Air Filters for improved performance with the comfort of oiled filtration technology for those looking for horsepower.
