Show original supplier description
The Process West Top Mount Intercooler (TMIC) is engineered to significantly enhance the performance of your 2008-2021 Subaru STI. The intercooler features a robust bar and plate core measuring 530mm x 193mm x 90mm, offering a substantial improvement over the stock unit. This upgrade kit includes the Process West Silicone Y-Pipe, a critical component that connects the turbo compressor outlet to the intercooler. Unlike many aftermarket Y-pipes that can lead to uneven charge air distribution, Process West's design ensures optimal and uniform flow to the entire intercooler core. This is achieved through a carefully engineered shape that effectively distributes the compressed air, maximizing the efficiency of the intercooler and contributing to consistent performance gains. Installation of the Process West TMIC is designed as a direct replacement for the factory intercooler. However, some users have noted that fitment can be tight, and potential contact with components like SPT heat shields may require minor adjustments. The included Y-pipe is also crucial for achieving the full benefits of this top-mounted intercooler system, providing a well-distributed charge air flow.
