08-14 STI Ultimate Cooling Bundle

Cooler. Stronger. Built to Handle More. The GR-chassis STI has long been a fan-favorite, but once the mods start stacking up, so does the heat. That’s why we’re offering a package that takes cooling to the next level. This bundle includes the GrimmSpeed Front Mount Intercooler Kit and the CSF 42mm Race-Spec Radiator, giving your 2008–2014 STI the cooling power it needs to stay consistent under pressure. The EJ engine is a classic—but it gets hot fast. High intake temps and rising coolant temps can limit your power and stress your setup. The GrimmSpeed FMIC combats heat soak and keeps your charge air cool, while CSF’s dual-row aluminum radiator handles coolant temps with ease—even in aggressive, high-boost builds. Together, they give your STI the breathing room it needs to perform. Whether you’re logging long track days or just making the most of every on-ramp, this combo keeps intake and coolant temps locked down—without cutting corners. Plus, when you bundle the two, you save compared to buying them separately.
