coolant line in lower intake needed ?

[speedtrip]

Sold my cobra intake and got holley systemax. I didnt remove coolant line nipple that threads into lower intake on rear passenger side. The small coolant line goes from heater coolant hardline to the nipple threaded into lower intake. On my used systemax lower it was plugged off do i need this small coolant line and the nipple. If it needs to be hooked up where can i find the threaded coolant nipple. Thanks

The coolant line and nipple are for the EGR spacer. If you are running without EGR then you probably don't need it. If you are running with EGR then I would put a nipple in and and hook it up. On my TFS intake the nipple corroded and broke and I replaced it with a brass nipple from the hardware store. I believe that the threaded hole in the intake is 3/8" NPT.
