i just took off my front bumper and removed the stock air filter stuff and i see there is a hose connected to the old air box at the bottom. it looks like some kind of sensor, it has a spring loaded pin and its a disc shape, what is this thing ive never seen it and i dont know if i need it attached to anything.

im installing a cheap ebay air intake system and i dont know what this thing does lol!

any help is appreciated

Are you talking about what's circled in black?

Just make sure you plug the hose that goes to the intake once you have removed all the bits.
