If an air box is utilized, it must be in stock form with NO MODIFICATIONS to the box or the inlet tubes. Air boxes may have up to 3 inlet tubes, each not to exceed 29mm +- 1mm inside diameter and 95mm minimum length. Approved air boxes are limited to CIK approved and RLV. Note special requirements for S5 (see RULEBOOK).
