Header question - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

So I'm installing a obx header on my 92 240sx coupe. (Ka24de) I removed the first o2 sensor then I looked down and noticed a pipe going to the mine pipe. Ill attach a photo of what I'm talking about.

My problem is I don't know what its for and my header doesn't have a bung for it.

well doing more researching I found out it the AIV and it can be removed.

There is an actual part number for a bolt that fits in that spot. of you can just weld it over. Don't forget about the egr tube also.
