Does anyone know what this is on my cold air intake?
So I bought 2003 350z from this old retired guy. I go to smog it and it fails smog because of the cold air intake. Im not too concerned about the cold air intake I can just go ahead and reinstall the stock intake. There is however this weird sensor that seems to be ziptied onto the intake and I have no idea what it is. I thought it was the mass air flow sensor but it seems to be a second sensor thats sliced into some other wires that I dont even have a clue about. Idk what the purpose of this sensor is and Idk if its even safe to take it off.
Im just wondering why tf theres 2, I wanna put the stock intake back but that second ziptied sensor is literally spliced into some other wires thats connected i to the maf sensor.
That's a Fetzer valve. You fill it with 3-in-1 oil to modulate the phases of the piston return springs.
I had one on my car, had to remove it, too much power for me.
I can't imagine having two of them.
