I have a Milltek TBE and a Forge Twintercooler I don't need actually. I fancy a THS, but even yet havent seen any reports that prove which intercooler is actually the most efficient or best for the Leon. I am still not fully convinced the Forge is the best option as it may catch all the cold air from the front of the 3 other cores, but is that at the expense of cold air getting to the a/c, intercooler and radiator cores?
