How to retro-fit the GTE air intake to a Mk7 Golf

[golfdave]

Great stuff here! Looking to replicate your GTE air mods. How many holes are drilled in the third chamber (far right, from the front) of the blocked off portion? Your pics don't really show it well. Looks like maybe 2 or 3? I'm trying to match the unobtanium OEM part as closely as possible.

Can't remember but looking at the photos I say 2...in the far right side..

The entire front of the vehicle is a space with high aerodynamic pressure, so the whole system behaves like connected vessels. For vehicles where the air box is located on the left side, the hole is unnecessary, but for vehicles where the air box is on the right side, the hole is part of the ram cooling system for the turbocharger and the emission control system. By the fact that the air is sucked in substantially at a right angle, the water droplets are separated as they have a higher kinetic energy than the air. By the way, VW has solved this whole system very well and with different types of air intake on an identical air supply system to the engine, both financial savings and different requirements for the amount of air supplied to the engine are achieved.
