Doing a GTi-R swap into a P11 Primera. Can someone tell where does the line off the block box to the back of the intake go to? It is the one that has an outer covering that is perforated...kinda like how the fuel lines are wrapped. Thanks in advance.

Some pics of what your describing would be good, as it could be a bunch of things...
Check to make sure it is...

the brake booster hose?
idle control hose?
Hang on... Could be the oil breather hose!
Post a pic in the Pulsar forum and I will tell you what it is
