Hi everyone! I'm currently struggling to decide what intercooler to go with on my s1. It's standard at the moment but I plan on eventually getting it to stage 3. However I don't want to fit parts that are only suitable to a stage 2 then have to upgrade again. Obviously airtec do a kit as well as wagner, pro alloy and forge. Are wagner and pro alloy really worth the extra money as they nearly double the price of the one airtec is offering? I don't want to cheap out but at the same time is it neccisary? I plan to get an is38 and run it around the 400 - 450bhp mark. All advice appreciated!!!
