Can anyone name this plug? It's a 12mm Allen Socket that gets it out. It's not listed in the specs nor referenced elsewhere. Perhaps the owners manual, but I didn't see it. There's two more on the intake side of the engine, one under the breather (OBD0-1) and the other is just above the thermo switch (near the knock sensor for GSR's).

the one on the back of the block is just a freeze plug. it should be a 14mm not 12mm. alot of people use that port for a catchcan

>sigh< Awesome. I can't find any part numbers for it.... kinda implies it's not to be replaced, I guess. To the junkyard.
