This hose and plug kit is designed to enable removal of the noise pipe (engine amplification pipe) on any transverse FSI or TSI vehicle which has this pipe attached to a 40mm provision on the upper intercooler pipe just before the throttle body. This is required on the TSI engines equipped with the noise pipe to faciltate fitment of the Forge TSI catch tank kit, unless some other method of noise pipe removal has already been employed such as as DIY plug solution or a replacement intercooler pipe that bypasses this connection altogether.
