Hi All

My girlfriend recently bought a 2014 1.6 petrol RCZ. This morning, I went to check the oil and noticed a stray brown connector under the bonnet.
Can anyone enlighten me as to what this is?

It’s because of the aftermarket air intake pipe you have on it, there is nowhere to plug the air sensor into with them.
Yellow circle shows where it should be. Can affect mpg and a few other things, thread link below showing another one ‘modified’ with bits left with no homes.

I disabled mine when I fitted silicone intakes its a "Wet Sensor" plugs into the socket on the bypass hose for the oil mist vapour residues or in layman's terms its basically a heater component for the PCV system relating to moisture build up if your engine has regular oil services it will never hopefully be needed to operate
