Depends if you are doing an intercooler also. If you are not doing an intercooler you go from the throttle body to the nipple on the back of the Gen V and block off the EVAP port.

2) Second modification you must make is the PCV system extension. If you look at the Gen V, and locate the EVAP sensor, look to the right, and you'll see a small nipple. This is part of your PCV system, this MUST be utilized, or you WILL have a vacuum leak!! Below are your choices:
  • You can run a tube from this nipple, to the air intake, this inlet must be located behind the MAF sensor, but before your throttle butterfly. In the LS1/Northstar setups, this is easily done by threading a tube into the air intake between the MAF sensor and the throttle body. On the L67 throttle body, it’s a little more involved. There is a brass plug on the bottom of the l67 tb, drill out the plug then tap it.
  • You can cap this nipple off, and run a breather on the front valve cover. (***NOTE*** this allows un-metered air to enter the PCV system, and may cause problems down the road)
