there is a sensor i believe on my intake manifold on the right side with a white plug...what is this sensor and is it needed when swapping a sohc into a b18a1 because i believe my del sol hardness does not have this plug. Thanks

 

Dude...its the effin IDB plug. everyone knows that

 

IAT- intake air temperature sensor.

 

ok thanks...my single cam should have that plug right? as of what i read it should be on the side of behind the intake manifold? Can someone just confirm this
