Max Cooling Bundle for 2008-2021 Subaru STI by GrimmSpeed
The 20152021 WRX STI is one of the most capable Subarus ever built, but the stock cooling setup leaves plenty of room for improvement. Thats why we put together the GrimmSpeed Max Cooling Bundle pairing Grimmspeed Top Mount Intercooler Kit with the CSF 31mm High-Performance Radiator, designed to keep your EJ25 running stronger, longer, and cooler under pressure.
This combo eliminates two major factory weak points, delivering reliable performance whether youre canyon carving, daily driving, or chasing numbers at the track. It’s designed to keep your STI cool and consistent, no matter how hard you drive. The GrimmSpeed TMIC drastically reduces intake temps, while CSFs 31mm all-aluminum radiator boosts coolant efficiency with track-tested durability. It’s a must-have pairing for drivers who demand more.
