Have you noticed a difference in performance between the K&N and Hector'* filter on the ADTR? Or do you still have to make some runs? Seems like the K&N would allow much better airflow.
I did notice a difference, but the old cone needed to be cleaned. To be fair, I'd have to clean it and compare them. The K&N, with over twice the surface area (larger filter, and deeper pleats) won't have the dirt effect. At the very least, I'll have good flow for longer.
The real gains (I believe) are from the laminar airflow. This has a true velocity stack on the end, which forces the air coming in from the sides to flow straighter. Kind of a venturi effect.
As far as the CAI is concerned, I can't say for certain yet, cuz I put on the MSD coils at the same time. I'll be collecting data on IAT temps on the way home from work tonight though. I'll let you guys know what difference it makes at 30 and 60 mph.
