Name that port...plz
It's on a S5 JDM 13B

I'm putting the final touches on my engine and I can't figure out what this port is for. I cant' find it in the FSM and the port is not tapped on an old N/A engine.

yep, its for the S4 knock sensor. the S5 irons were tapped for it as well but the knock sensor was moved to the front rotor housing.
the threads do not go all the way into the iron so it can be left as is.
