It's just like any other intake. It's not hard.

Make sure you do other mods to back it up though.

Exhaust
Power Wire
Throttle Body (I'm getting Fastman TB)

I have a 3.7 so I won't be doing exhaust. I will do an intake along with the power wire if I install a Fastman throttle body.

Don't just do a CAI alone.

There is absolutely nothing wrong with doing just a CAI alone???

Naw, there is absolutely nothing "wrong". You just won't benefit from it alone.

Well you are incorrect. I found a benefit by doing it. I'm also not the only member who has done it either.

Why don't you and your "white chocolate" go to another thread. Lol. J/K. In my opinion and experience with a Subaru STI, I wouldn't do an intake alone.

Re: cold air intake
 
I'd like to know what benefits you got from it. Gas milage?

My gas mileage went up and my friend in the city owns a dyno at his performance shop. Every year we get to have 2 free dynos. I was able to gain 7.3 hp from stock, to intake.

Benefits WILL increase with more stuff, tuner, tune, exhaust, etc etc, but you WILL see a gain from an intake alone.

Plus they sound badass...enough said.

Re: cold air intake
 
7.3 at how many RPM's? I'm assuming you'd be driving all over town at WOT.

I have the Fastman TB on my WK 4.7 and I'm waiting to see if Bwoody come out with a CAI before I make a decision on what to buy. I didn't need to give it any thought because I was running a fastman TB and CAI on my previous lifted Jeep Cherokee. The '08 4.7 is already pretty responsive but the TB made it more so and more usable in the hills. I am not yet running a lift or larger tires but my experience with the XJ showed the advantage - the lifted XJ had struggled on my hilly commute to stay in 4th gear and would never get into 5th. After the TB/CAI I was able to get back 5th and stay in 5th for the commute. I had tried the CAI on it's own and saw a small improvement but it was only after adding the TB with the CAI that I saw the noticeable difference. This was general driving not WOT but it did help there too.

If you are thinking about this just to say the newer WK TB's plastic is fragile. Don't overtighten the clamp when installing especially if you have a modified TB that has less material.

I'd buy a Fastman TB before I buy a CAI.

Edit: And did I mention that the Fastman TB will save gas. You'll save gas by actually using less power. And it's cheaper than a CAI.
