I would take $250 for the CAI and will sell them seperately. I think you are better off with a custom tuner than the pro cal tuner. It will give you more power and more options. Most mods require being retuned which requires a tuner. Before buying a tuner find a local mod shop with a dyno machine and see what brand he is used to.Will you sell the parts separately? I would be interested in the Cai if the price is right. I know you said make an offer,but I don't have a clue what it's worth used without the tuner.
