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. Factory air inlet ducts use sound baffles and awkward bends which restrict flow. Our Cross-Link polyethylene air ducts are sculptured to give the engine less restrictive breathing. Incorportating larger diameters and unique bends that cant be duplicated with metal ducts allow maximum airflow velocity and throttle response. This model includes a Pro-5 filter which gets reoiled every 10,000 miles and serviced every 50,000 miles with cleaning kit P/N 5100.
