Awesome, thanks for the write up... I've also got a '15 WRX CVT, ordered the Mishimoto CAI w/ box and just got shipping notification tonight, should be here friday... I'll definitely refer to your post while installing.. I know Mishimoto claims some performance gains, did you notice much or is it negligible? Watched your video too, kinda hard to hear it well in the cab, also sounds pretty windy, is it pretty loud from inside the vehicle? Thanks!
