The Grimmspeed Charge Pipe Kit is the perfect addition to the top mount intercooler for the FA20DIT WRX. The mandrel bent aluminum piping will send pressurized air straight to your intercooler with very little restriction of flow. A completely custom silicone coupler will fit the stock turbo style outlet easily and the bypass valve plumbing is exactly like factory as well. This will fit the factory bypass valve or any stock style valve. Powder coated black piping is a perfect functional look in the engine bay but enough to know you've upgraded to nice hardware. Grimmspeed always does a great job with fitment and function and the top mount intercooler piping is no different. All hardware is included to make this installation a breeze.
