Unlike the 2.0T FSI Motor before it, the 2.0T TSI Motor has no easily accessible vacuum or boost source. Thanks to some clever engineering we have produced an easy, reliable, and economical way to tap into the the 2.0T TSI Motor for both boost and vacuum. Our TSI Boost Hose is constructed of 5-Ply Silicone with Nomex Fibers. We chose to use Nomex Fibers in place of the standard polyester fibers because of Nomex's better strength and heat resistance. Re-using the OE fittings, our Boost Hose is easy to install and will maintain factory reliability. Our hose design allows for integration with any aftermarket Boost Gauge or Diverter Valve. If our hose is purchased for use with our Mk5 Vent Mounted Boost Gauge Kit or 2.0T Mechanical Diverter Valve, we will include all items necessary for installation as well as detailed instructions.
