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. The Periscoop uses Volants sealed air filter box and high-velocity air intake tube. The air filter box lid also incorporates a hood seal adaptor that funnels air from a hood-mounted snorkel which extends up the passenger side of the vehicle to the roof-line. The snorkel scoop uses a polished aluminum front cover that looks great, and prevents larger debris from entering into the air intake system. 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.
