It keeps hot coolant out of the throttle body. Heating up the throttle body will heat up the air going through it. It helps to keep lower intake temps for denser air from the intercooler, which in turn helps increase power.Wow, awesome thread and tons of great pics! Of course this pops up now when I already went and manually installed a switch to control the boost gauge illumination functionoh well haha.
One question though about the "free power mod" here, dont really understand this, if this is better/more power why is it setup the way it is from stock? Just curious.

No adverse/negative affects? Guess I am just confused why Nissan had it set up like that in the first place? sorry, just trying to understand it moreIt keeps hot coolant out of the throttle body.

Mainly for the Northern guys who see very cold temps. It's a "de-icing" feature to prevent the throttle plate from icing over and sticking open in frigid temps. I had it bypassed like that and drove through the snow storms we got down here with no problems with throttle plate icing or sticking. ECU doesn't care about bypassing the coolant because it has no way of telling.No adverse/negative affects?
