Damn....lucky lucky lucky. I had to buy mine at full price.I got my intake for $40 brand new off ebay. But be careful about ebay, alot of people sell crap. I got the HKS super mega flow intake, I like it, sounds good and adds a little HP.
Regarding prices, you are looking at ~$200 for a CAI. Couple of websites you may want to check out: option auto , nopi ,
