After 8000miles I removed my intake today for a couple of reasons:
1. Moving back to Cali, and may need an emissions test.
2. May be towing a trailer and low end torue is more important than high.
My mpg's went back up about 2, however high speed passing may have suffered a tad. It should be noted (specifically now that it is warmer outside here in TX) that usually after prolonged driving that extra high rpm responsiveness seems to wane. My engine bay should be less dirty since the stock airbox is back in the inlet (The intake was very clean on the inside though). I have ordered a KNN filter, and will not be reinstalling the C/S. While it provided great sound, esp with the C/S exhaust, it is not a big improvment on the 2.0L compared to the 2.5L. Also, the inside of mine has scorch marks near the motor side, and around the tube that goes into the intake near the motor. Probably from redline shifting but not present on my stock intake (granted, less airflow). The car still sounds great with the C/S exhaust only and based on cruise, my mpg seems to be higher than when it was just stock. Maybe when my motor is out of warranty (if I even keep it that long depending on the availability/price of the diesel) and I look into forced induction I'll consider a short ram but for now, I won't use it on this motor. A 10 HP/Torque gain for the 2.5 may be worth it, and maybe if you live in a place with cooler temps but for my 2.0 in TX, and CA no.
