The factory front mount intercooler on your Mitsubishi or Subaru is inefficient for higher boost levels and a bigger turbo. The Injen front mount intercooler kit is designed to fill in that gap. As you turn up the boost on your stock turbo, the small turbo ends up spinning much faster, and generates a lot more heat. The Injen Front Mount Intercooler kit combats that heat with an ultra efficient intercooler core, and short running intercooler pipes that are designed to reduce piping as much as possible for even further efficiency.

For those of you who have aftermarket upgraded turbos, the amount of air the bigger turbo flows can't be supported by the small and restrictive factory intercooler. The Injen Front Mount Intercooler Kit is designed to allow much CFM through the core, and at a lower pressure drop. This creates more power and torque even on a stock setup!
