Nice pics of your car! Looks like you already did some modifications. I live in Honolulu and own a 2012 black 370Z. I have been thinking of the cold air intake add on. How do you like it? Do you notice a big increase in power? Also hows about the wheel spacer - does the car run any rougher or wheels off balance?

I didn't have any issues with the spacers. It still ran smooth with no vibration/balance issues. The Stillen intake and exhaust went in at the same time. The Z makes great sounds with the two of them at high RPM. Power was up a bit too.
