Throttle body inlet pipe for NB

As used on our turbo systems. A custom-formed silicone hose to mate up to the throttle body. It includes a 1.375" outlet for a bypass or blowoff valve. The aluminum pipe allows you to connect it to your intercooler outlet pipe and will not rust internally like mild steel pipes can. 2.5" inlet. Please note that this no longer has a port for an intake air temperature sensor. For a number of reasons, it's best to put that in the outlet tank of your intercooler (if you have such a sensor). 

It will work on a MSM if you have an FM intercooler and you also install our intercooler outlet pipe. 

For the 1999-05 throttle body. If you have done a 1.8 swap on your early car, you'll need to match this pipe to the throttle body you used.
