After I had installed my cold air intake, and removed the ram air duct in the front, I had noticed that I had some type of sensor that was bolted to the ram air duct dangling without a home. What is this sensor for, and does it have to be in a specific place?

 

this is a temp. sensor. just make sure you take the plug housing out from the ram air duct and put it back on to the sensor. then just place the sensor anywhere secore. i ziptied mine to something near my intake.

 

I've noticed that my Maxima has a boost sensor while my friends do not. I don't know what the hell it is, but I know it isn't the temp. sensor because that one was attached to the stock filter box and is now also dangling around with my boost sensor. What the hell is a boost sensor?

 

I have a boost sensor also on the 'black scoop on top of the grill'. I have a '99 Max..is this only on those Maximas?


Also what is that scoop for anyway?

 

I wish I knew...but I hope it doesn't affect anything being ziptied to my battery cable

 

Dude, if you take off the black duck/scoop, your car will sound a lot louder. When you get an intake, you have to take that black scoop off. I took it off even before I got my CAI, and it sounded badass.
