Aftermarket Parts

[Drummer4lifex]

I just bought my Nissan NX2000. It's a 1992 and it only has 56000 miles on it. I was wondering if any of you knew a good spot to find aftermarket parts. It already has a completely modded suspension, a full custom exhaust system and a K&N Air Filter. Im looking more particularly for intake systems, I dont know if mine's as high performance as I want. I'm looking for cold induction systems, but maybe I don't know much of what I'm talking about because I really dont know how good my intake is. Also if anyone knows where I can get custom fit subwoofers, or body kits and stuff like that, that would also be appreciated.
