No problem, dude. i wouldn't be too concerned with counterfeit parts at this stage. I mean, a CAI is a fucking tube with a filter on it, and a sway bar is a sway bar for the most part, so I wouldn't invest a shit ton of money in either one, imho. i've got an aem cai and a dc sway bar...both of which i have been extremely happy with.
i don't have any specific sites that i use as I had the shop that dropped my jdm b18c type r motor in my honda grab all of the parts, but you can check out the honda-tech.com forums for some good info. you should be able to find some reputable sites and good info there. that's where i usually go when I'm trying to trouble shoot a problem. a lot of smart dudes over there.
