As more and more aftermarket products come out for the Juke they become more technical and specialized beyond extra plastic body molding or a new air filter/intake.
This new intercooler by Forge Motorsport in the UK is one such example. While the new part will bolt up in the same location it provides substantially more cooling capability than the stock version and can assist in horsepower production and overall engine cooling. At 499 GBP its not cheap...but then again, horsepower usually isn't.
Forge also makes an upgraded blow off valve and recirculation valve for the Juke as well. All can be seen at the link below.
