I have a Rebel, thought about cutting the two front and reversing them. If you noticed, they are facing the wrong way.
I designed and 3D printed the vents in high temp PC. Ending up not cutting the holes, wasn't sure if I was going trade the truck or not.
Next option was either make my own CF hood or purchase one. There is company in US, that makes CF Rebel/Ram hoods.
They have some good reviews and some bad. Since I'm in Canada, cost to ship/duties wasn't worth it.
You would need to also Tune it if you were going to do anything as well.
Currently I have S&B CAI on my Truck. Doesn't really do anything but make Truck sound better. Plan was to redirect the vents into CAI instead of the stock location.
I disagree that more air doesn't affect performance, it does. But there is more than just adding CAI.
