Description

The GrimmSpeed Billet Top Mount Intercooler Kit represents an advancement in cooling performance for Subaru vehicles. The intercooler core utilizes a bar and plate construction, measuring 19in x 7in x 4in, offering a significant increase in volume and flow area compared to the stock unit. GrimmSpeed emphasizes quality and reliability, with each intercooler being pressure tested in-house before delivery to ensure it is sealed and ready to perform. This top-mount intercooler does not require a tune and can be safely operated with the factory calibration, simplifying installation and integration. The kit is compatible with the 2022+ Subaru WRX (VB models including Base, Limited, Premium, and GT). It also fits the 2019-2023 Subaru Ascent, 2020-2023 Subaru Legacy XT (Sport, Touring), and 2020-2023 Subaru Outback XT (Base, Limited, Touring) and 2021-2023 Subaru Outback Wilderness.
