Our air intake system utilizes 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 a Pro 5 filter which gets reoiled every 10,000 miles and serviced every 50,000 miles with cleaning kit P/N 5100. With Volant you have an intake that delivers excellent horsepower you can feel and fuel economy that puts some money back in your wallet.
