An off-road vehicle has a frame with a floorboard extending laterally over a middle region of the frame. The floorboard has a upward projection that defines a tunnel. At least a portion of an air intake system of an engine of the vehicle is positioned within the tunnel. A foot pedal is disposed in front of a seat such that a driver of the vehicle can operate the pedal by foot. The tunnel has a surface that is laterally adjacent the foot pedal such that the foot of a driver can simultaneously contact the surface and the foot pedal.
