I am going k04 with the APR sale going on and am just trying to finalize my decision on an intercooler. The AWE TOP and hose kit with the s3 intercooler core off ECS seems like the cheapest option for an upgrade (other than godspeed which is yet to be tested). While I think the APR intercooler is the best, I'm not ready to drop a grand on an intercooler at this point when I'm going to buy the k04 kit and a DP. At any rate, with eurojet supposedly being better than the s3 intercooler, I haven't seen any proof of it, plus the issue with not being sure if they are even open and running, that is kind of off the list. BSH would be an option, but they clearly have a mk5 option but nothing for the mk6, even though the cars are similar. I came across some data on mk5 that I thought was worth sharing comparing the s3 vs. stock. Here it is for your knowledge. Just thought i'd share:
