Yeah this is really a dumb question because it is obvious but I'm a noob at some things. If I got a CAI and a 65mm TB from Focus Sport, I would need to get the car re-tuned or else it may be to running to lean? Please explain this for me. Thanks.

Shouldn't need to. Might help, but I don't think its a need to issue. And, just so you know, FS only sells the Cossie TB for us which is a 67mm.

I am an uber noob, I feel dumb as [censored]. Well I dont exactly wanna tear into the motor because I just got the car 3 days ago and the warrenty is good for 6 years. Hentz the just bolt on parts. Though I would like a new exhaust, what about tuning for that? Yes or no? Or with all three should I get it tuned?

Shouldn't need tuning for the exhaust either. I'm running CAI and Exhaust with no tuning and have no problems at all. Don't worry, ask all the questions you want. Thats what most of us are here for. We all gotta start somewhere.

The stock st throttle body is supposedly 65 mm. And can be had for under $100 bucks.

You shouldn't need tuning unless you fool with the MAF unit, cams, compression, or go FI / NO2

But it might be helpful if you get a header, to take off that pesky CEL.
