Abstract: An air box assembly attached to an outdoor power tool for reducing sound generated by an engine is provided. The air box assembly includes a casing formed as an upper and lower housing attached to each other to define an enclosed space. The casing includes at least one air inlet and an air outlet. At least one filter is positioned within the casing. An air guide assembly is positioned within the casing such that the flow of air to the engine passes through the air guide assembly as it travels to the engine and sound from the engine passes through the air guide assembly as it exits the air box assembly. The air guide assembly includes a plurality of fluid pathways therein, wherein the fluid pathways are in fluid communication with the air outlet of the air box assembly.
