The intake volume increased by around 20% improves the response behavior and reduces the extreme pressure fluctuations of the standard very small airbox. This modification is also often combined with intake funnels. It should be noted that the air correction of the standard air filter is no longer required. The main air correction nozzle and/or the jetting in general must then be adjusted accordingly.
