  • Air delivery system for an engine
    Patent number: 10837413
    Abstract: An air delivery system for an engine includes a first air filter, a second air filter, a first conduit, a second conduit, an air box, and a third conduit. Each of the first air filter and the first conduit, and each of the second air filter and the second conduit are disposed at a first angle with respect to a lateral axis of the air box. The first angle is adapted to limit restriction to flow of intake air from each of the first air filter and the second air filter toward the air box. The third conduit is disposed at a second angle with respect to a longitudinal axis of the air box. The second angle is adapted to limit restriction to the flow of intake air from the air box to the engine.
