Just noticed some intercoolers on ebay designed for the S4, not a generic one with a bunch of random pipes and fittings. Now my other car is a Toyota MR2 and ebay intercoolers have a pretty good reputation on them other than the pipes and clips are often of poor quality. The concensus is most fo the cores come from the same factory no matter where you buy the kit.

What are peoples thoughts? Got to be easier to fit than an FMIC on an S4.
