Purchased from: Wehrli Custom Fabrication - WCFab

Purchased this with the two intercooler pipes, but put this on first. This, along with the Banks Derringer tuner, gave an instant boost pressure bump and more roar from the turbo. I may or may not have plugged the PCV input temporarily to see if it made a difference or not.....it did. I'm looking forward to the WCFab cold-air intake for the '21 L5P to match up with this.
