hey guys ....i was thinking about the piping, and it came to my attn....

the way my car is now as NA, the intake hose has a air temp. sensor i believe (pointy black thing). i was wondering, when we go turbo, do we still gotta use that thing??

we just make a hole in the intake and plug it in??

IIRC, it needs to go into the intake after the intercooler because it is an important sensor (don't leave it off) and the pressurized air will be heated, a condition the engine needs to know about.

The temperature of the air going into the tb is one of the variables the ecu takes into account when determining how much fuel to spray through the injectors. Hot air is less dense than cold air, so hot air needs to be a bit leaner than cold. If you just have the sensor hanging out in the engine compartment, the ecu thinks the incoming air is whatever the ambient temperature is (say, 70 degrees), whereas your engine may actually be getting air that is 150 degrees or so.
