GTP's Notes:

*When buying used you will often have to reuse the vacuum rails from your existing intercooler.

*You should also consider new hose clamps for the intercooler hoses as these need to be very secure.

*Additionally, when removing the stock intercooler hoses, it is easiest to remove the throttle body to get at the metal hard line bolts between the turbo and BPV. The metal hard line is not used with the STI intercooler or hoses.

*The throttle body gasket is re-useable most of the time but, it may be a good idea to pick one up just in case it is damaged while removing it.
