Need Help/Advice installing CAI 96 318IS

Hey Everyone,

Recently someone had given me a AEM Cold Air Intake. I wanted to install this, however I have a few questions before doing so. I plan on just removing the airbox. Leaving the Mass Air Flow Sensor still on before the pipe and intake. There is however another sensor that is plugged directly into the Airbox. Now before I mess something up, what the heck is that sensor and do I need it?

Pics and hints would be appreciated. Didnt know if I should drill a hole into the intake to plug that sensor in our not. I turned the car on with out the sensor and nothing happened. Let me know what you think, thanks.

what i did and most do is zip-tie it to the frame rail below where the airbox was, all it is is another sensor, what it does im not too sure , i used to know but i wont claim to remember. all i remember is there is coolant in the lines that lead to and from it. it wont affect your install, just ziptie it out of the way and so it doesnt flop around and potentially hit a moving part.
