Hi everyone, I'm sorry this is probably a noob question, but I can't seem to find what this part is called. I tried describing it and what not, but the search bar is sending me for a trip. Please help me.

2007 MS3 (not my picture, found on google. if this is your car - thanks).



It's the hose/line that is highlighted green. The Cobb manual calls it a vacuum line but the Mazda dealership guys don't know what I'm talking about. If you have a part number, that would be even better. Or if you have the OEM part and willing to sell it, I'm looking for one.

Thanks for your help.

Thank you both for your help.

I'm not sure what the "pre-smoking turbo fix" setup is, but I current have a HPS SRI in my car that is not certified for use in California. I have recently purchased a Cobb SRI to replace it, but the line in question was removed when I installed the HPS since it came with a silicone tubing, whereas the Cobb does not.

I was able to use a heater hose as a makeshift line, but I figured that might be a cheap part I can get from a junk yard or off the forum if someone totaled their car, but I had not idea what to call it to even start looking.

Is there something that I should do to prevent the smoking turbo while I am replacing this line? I'm at 127K without my turbo smoking.

I'm a bit rusty on this, but that picture I found/posted jogged my memory a bit.

Certain 2007/2008 Mazdaspeed3s had issues with oil not draining from the turbo and smoking producing lots of oil smoke in the exhaust. There was a fix for that, and it came by default in the 2008.5-2009 mazdaspeed3s, and was likely also fixed under warranty on the pre-2008.5 models (once again, per the picture).

As a result of the re-routing of the vent hose, there were also pre and post smoking turbo fix SRI/CAIs. I guess you just found that out the hard way.
