Product Description

The Perrin PSP-ITR-325SL Top-Mount Intercooler is a high-performance direct replacement for stock intercoolers on 2015-2021 Subaru WRX models (VA platform, AWD). Its 66 % larger bar-and-plate core (523 cu in) significantly reduces intake-air temperatures, delivering a steady 10+ WHP gain and improved torque without requiring any engine tuning.

Installation is quick and hassle-free, taking approximately 1.5 hours with no ECU flash required. The intercooler comes pressure-tested to 50 PSI, includes a high-quality silicone throttle-body coupler, and sports a durable powder-coated silver finish. Secured via pre-threaded stainless inserts, it offers reliable mounting and long-term durability. Backed by a five-year manufacturer warranty, it's an ideal upgrade for WRX enthusiasts seeking cooler charge temps and enhanced performance - all without breaking emissions compliance.

**Fitment confirmed through 2021; 2022+ models unconfirmed.** No evidence supports fitment on other models like Forester XT unless Perrin issues official documentation.
