Billet Top Mount Intercooler Kit (Black)

• 2022-2026 Subaru | WRX

GrimmSpeed Billet Top Mount Intercooler Kit (Black, GRM113049BLK): we have raised the bar again

GrimmSpeed 3D scanned its R&D 2022 WRX and designed this intercooler to fit the tightly packaged engine bay with a focus on increased airflow, reduced restriction and less pressure drop across the core. It uses a 19in x 7in x 4in cross flow bar and plate core, which GrimmSpeed says provides a 63% increase in total volume and 209% more flow area than the stock top mount, while keeping factory fitment of the charge pipe, throttle body and hood ducting interface.

The standout feature is the 4-axis CNC milled billet aluminum end tanks, styled to suit the VB WRX. Installation uses the same quick release double O-ring technology as the OEM unit. This listing is the black finish.
