Actually not near as much a HP gain as the VW in that article.....(m)
the current Audi cold air intake systems use a different route and different tubing then the VW & the overall "cold air" that is recieved into the Audi system is not as efficient. Therefore we see some HP increase but its more along the lines of 5-8 hp gain. About the same as a K&N filter. Although I do agree that the EVO system "looks" nice & professional.

I'm pretty sure APR determined that the OEM box flows as much as an intake
There is a reason why they recommend the stock airbox for the GT25 upgrade.
And my experience with turbocharged cars in the past backs that up. It's always increased responsiveness, but adds nothing to the powerband.

How about this
Granted it's an S4, but the results are still pertinent. The 1.8T and S4 use the same design airbox.
