Is anyone running the AEM intake with a 3 port BCS? I want to run this setup but I'm not sure what to do with one of the vacuum lines since the AEM intake has two vs the one that normally comes stock.

 

Stock intake has two connection ports, one for the stock BCS and one for the valvecover breather.

 

You can cap one of those off, that's what has been done on my car. I don't remember which was capped on the intake, and i can't check as my car is at a body shop, but you can cap one off. This is assuming you're running a 3-port

 

I guess I could cap one off or just run both vacuum lines from the intake into the splitter that originally ran with the stock BCS.

 

Just cap off one of the port from intake arm and use a spliter for the two little hose .
