VW’s Mk5/Mk6 TSI engine bay doesn’t present much of a challenge to a skilled fabricator. Once the
factory airbox is removed the engine bay is wide open for air intake interpretation. There’s enough
room to experiment with a dozen unique airflow ideas. There’s also plenty of room to make mistakes.
When we took on the Mk6 TSI air intake project we focused on our velocity stack design and smooth
transition principles. The space defined itself, leaving us with an intake that looks great and truly performs.
Fresh air meets the front grill, flowing into the OEM air inlet and splitting off 90/10 into the stainless
steel heatshield. Air is then delivered to an oversized filter where it is drawn-in by our CNC machined
velocity stack. As air passes over the velocity stack it is organized and accelerated into the intake elbow.
After an effortless transition into the MAF housing, intake air makes a steadfast run for the turbo. Power
gains are a welcome side effect.
Under the hood, this intake system is perfectly integrated. The heatshield follows the natural lines of the
engine bay while making use of the OEM air inlet and airbox mounts. The intake elbow slides over the
MAF housing without altering the OEM location. Satin black powdercoat finishes off visible components
for a clean look. Secondary air plumbing is filtered, secured, and hidden from view.
On the road, this intake unleashes power and sound. The diverter valve is audible and the sound created
by the velocity stack can only be described as vicious. Substantial power gains can be felt throughout the
power band with no loss of low-end torque.
