So I currently have the stillen SRI and today I noticed this extra hose. I didn't see a place where this hose connected to but it looks like a breather hose?

Just curious if anyone has any idea what this is lol

 

Hard to tell from your pic but I believe that's the transmission breather hose, might be wrong

 

That's what I thought but wouldn't that just bring in hot air into the transmission? Sucha small hose lol

 

I'm going to take a look under my good when I get to my car, try and see where that hose leads too but someone here reported before it being some type of exhaust for the transmission

 

Yeah it leads to the transmission. You can see in the 2nd picture it's the smaller hose . I can't remember which intake it is but one off the intakes actually tells you to attach the hose to the intake? I can't remember where I saw it.

 

The R2C has a hole to clip it in so that it essentially stays in the same place like before with the stock air box

 

It's in the K&N video. I just watched it the other day. Responding to GNC's post two above this one

 

It is a breather hose. Heated oil and air in transmission must have an escape route or the seals might start to fail. Vent to outdoor air is solution. Size of orifice is determined by diameter of bugs that might want to migrate inside....

Notice it has a upside down bend, this helps prevent water from entering from that too big puddle that turned into a wading pool.

 

Thanks great information. So no need to mess with it huh?

 

Leave it alone. Or wait until NISMO makes a carbon fibre version
