The BBR Tuning Boost Intake Manifold improves efficiency and provides high performance for motorized bicycle engine setups because of its unique design. The Boost Intake Manifold also provides a threaded top screw for Boost Bottle Induction Kits and Nitrous Oxide Kits. Fits on most 48/66/80cc bicycle engine kits, it is designed for greater gas flow efficiency as well as an O-ring seal for a nice air tight fit that helps prevent any vacuum leaks that normally cause poor idle quality and bogging.
