In preparation for colder weather and an upcoming oil change, I took off my Injen CAI and put the stock airbox back on the car. I left the battery disconnected the entire time and it was my first step before taking anything apart.
Once it was all back together and I double checked everything, I started it up to check for any check engine lights etc. All was good. I took it for a test drive.
The Idle was particularly noticeable since I have a SURE RMM.
Additionally, I noted the breather setup for the Injen runs a straight piece of tubing from the side of the intake to the crank case vent connection. There's no PCV valve.
I am wondering if this has anything to do with the smoother aspect of the stock box, or if the lack of air straighteners in the Injen are more likely responsible.
Thoughts?

- Idle is lower, but also much smoother?
- Part throttle accelleration is much smother
- Throttle response seems a little better
