PERRIN Top Mount Intercooler – PSP-ITR-330BK (Black)

The PERRIN Top Mount Intercooler PSP-ITR-330BK is a massive cooling upgrade for the 2022–2025 Subaru WRX (VB) and select turbo Subaru platforms. Featuring one of the largest TMIC cores on the market, this intercooler dramatically reduces intake air temperatures—by up to 14°F versus the OEM unit—while supporting 600+ WHP builds.
