Not to burst your bubble, but if you have a a9L or a9p computer with wiring harness, you might be able to get $225.00 for it. The intake and rest of the stuff is pretty much garbage. Someone might buy the mass air because the need the stock electronics for a C&L but other than that, it's useless. Injectors sell for $10.00 a set of 19's, stock intake, $10-$25 if it's super clean. Stock throttle body, no one wants. I don't think your going to come close to $600, If you got $300 I'd be impressed.
