Im gathering up bolt on parts before installing them and getting tuned. I'm switching to speed density in the process

I was wondering for the SD intakes that do not have the plugs for the lines that hook up to the stock, and some aftermarket intakes, what do you do/what happens with those lines/ connections?

why are they not there on SD intakes?

Can i use a larger aftermarket intake as a SD intake by removing the maf adapter and keeping the connections on the intake?

 

They don't have them because almost everyone has a catch can and a aftermarket boost controller by the time they switch to speed density so there is no need.
I use stm's sd intake and just added a brass nipple for the valve cover as I do not need a catch can. I also use a 3port so I don't have it hooked up to the intake for my boost control.

 

So do you even hook up a vacuum line to that port?

 

Get an SD intake that does have port for that vacuum line and call it a day.

ETS Sells SD intakes that have it.

 

If you really want to reuse the lines,yea ditch the maf and leave your existing intake.

 

I don't care one way or the other just wondering if you can leave that port open. I have the ets sd intake and I was under the impression that was a pcv nipple

 

If you talking about 3 port ebc,then you can run the line from the port to intake pipe.or leave it not connected. I didn't connect .
