Hey there, welcome to FF!
The intake on these cars are a breeze for people who want to do CAI's. The only sensor you can really funk up is the MAF sensor, and that's pretty darn hard to do lol. All the factory stuff on there can go with no problems. I got the Steeda Short Ram Intake (some call it a CAI, but its really more of a short ram as far as design is concerned) and had it custom powder coated, but left all the rest of the intake system on below the intake. Tons of folks rip the rest of the stock monstrosity out though.
Here's a pic for some inspiration :P and if you have any questions, ask!
