From what I’ve seen, only one is really needed on the N14 engine - fit the catch can into the rear left side PCV hose that leads to the intake manifold.

Carbon build up was a problem on N14 engines. I haven't seen it mentioned on N18 and newer engines.

Carbon build up... Plz help...
Update: 4-3-13.
gawannamini has put together a good write up on cleaning the valves with the Walnut Shell Method. I created these steps before the Walnut Shell method was created. If you don't mind spending about $100, you can build your own Walnut Shell Blaster (minus the compressor).

This is a How-To on Removing the Carbon Build-up, the right way.
I couldn't take it anymore with the decreased performance. My car has 60K miles on it (I bought it with 50K a year ago) and I don't think the carbon build-up has ever been removed properly. The throttle was sticking, the performance was down and it just felt like the car was struggling.
I know there's a lot of people that swear by the Seafoam method, but I've run 2 bottles through my car in 4K miles and it's done nothing. I also got taken for $250 for a dealer method (while the car was in for other service) that was only a temporary fix (a few days and a warm fuzzy feeling).
So, I decided to tackle cleaning the intake ports/valves manually myself. I wasn't going to pay the dealership $$$$ without having some way of verifying it was done right and I just don't trust them. It's my car, if I want it to last, it's my responsibility.
After reading a few posts on cleaning the valves, I didn't see where anyone had done a full writeup on the procedure. I figured I would jump in and do the writeup, so others can do the maintenance, regain the lost performance and learn a thing or two about our cars.
The result? Amazing! I feel like my car runs brand new. The build-up on my car after 60K was extreme. I couldn't get a clear picture due to the location and lack of light, but trust me when I say it was extreme. After looking at it, I wasn't surprised it was running terrible. Now, the performance is back, the throttle works perfectly and it runs much smoother. I put in the BSH Oil Catch Can after I cleaned it which will definitely help reduce the buildup in the future.
Believe me when I tell you, you can do it. It's not major surgery and only takes a Saturday. I tried to lay out the steps as detailed as possible, for the inexperienced.
If you have any questions, shoot me a PM. Enjoy!
