The invention discloses an air filter air outlet pipe. The air filter air outlet pipe comprises a first air filter air outlet pipe, a third air filter air outlet pipe, a rubber sleeve and a second airfilter air outlet pipe made of an elastomer material, at least three circles of ripples are annularly arranged on the second air filter air outlet pipe, and the left end part of the first air filterair outlet pipe is fixedly connected with the right end part of the second air filter air outlet pipe. The left end part of the second air filter air outlet pipe is detachably and fixedly connected with the right end part of the third air filter air outlet pipe, the left end of the third air filter air outlet pipe is detachably connected with the right end of the rubber sleeve in an inserted mode,the right end of the first air filter air outlet pipe is fixedly connected with the air filter upper shell, and the left end of the rubber sleeve is detachably and fixedly connected with an engine connector in a sealed mode. According to the air filter air outlet pipe, the usage amount of the rubber hose is reduced, the part cost is reduced, the sealing performance is improved, the arrangement space is small, the interference between the air filter air outlet pipe and the peripheral parts is avoided, the abrasion risks are eliminated, the manufacturing process is simple, the manufacturing errors are reduced, and the vibration isolation performance is improved.
