Description Vehicle Fitment & Emissions Installation Instructions 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.
