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. Volants 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 a Primo filter which gets recoiled every 10,000 miles and serviced every 50,000 miles with cleaning kit P/N 5110.
