I find it's generally a good rule of thumb that the better the part, the less likely it is to be available used... I feel like I've been seeing a whole bunch of Alta intercoolers available for sale. Is this an indictor of problems or lack of quality or performance gains with the Alta IC?

I ask only out of curiosity, as I don't plan on replacing my stock IC any time soon - if ever - and I would probably only consider the GP intercooler. Is it really that hard to make a decent intercooler? Fitment issues aside, what separates a good one from a bad one?

 

I dout that it is a bad ic... It's just one of those things that is every easy to replace/take off your car.. To put it back to sock
