ETS Top Mount Intercooler

The ETS top-mount intercooler replaces the factory VB WRX core while retaining the original top-mount location and factory charge pipe. Its 21-by-7-by-4-inch core uses 34 charge rows, offset and staggered fins, billet inlet and outlet sections, TIG-welded construction, and pressure testing above 35 psi. It is intended for owners who want more charge-air cooling and heat-soak resistance without converting to a front-mount system. ETS lists 2022+ WRX fitment and offers the core in standard silver or optional anodized colors. The intercooler alone does not change MAF scaling, so a calibration change is not normally required; other boost or airflow modifications must still follow their own tuning requirements. Installation is a direct replacement with careful sealing and clamp alignment.
