i have a 90 crx with a d16zc moter what is the best cold air intake for it

 

ummm what? d16zc? is that a d16a8/9 zc or a d16a1 "zc" or a d16z6? Either way I have always assumed that the big name brand intakes like AEM are the ones that make power until I sat there and watch my friend gain 10 hp midrange with a J's Racing (you know the huge bulge slug shaped intakes) on his GSR civic.
