Mishimoto Thermostatic Oil Cooler Kit - Subaru WRX STI (GRB/GVB) - 19-Row

Mishimoto designs its cooling hardware to keep fluid temperatures consistent under sustained load, and this direct fit kit is purpose built for the Subaru WRX STI. A 19-row aluminium cooler sits behind the front bumper to make the most of available airflow, helping protect engine internals on track days or hard street driving.

This listing covers the Subaru WRX STI GRB and GVB chassis from 2008 onward, fitted with the single scroll turbo and unequal length exhaust manifold. It's available in silver (SKU MMOC-STI-08T) or black (SKU MMOC-STI-08TBK) cooler finishes - select your preferred option from the variant selector on this listing.

Important: This kit suits models with the single scroll turbo and unequal length exhaust manifold only. Vehicles fitted with the twin scroll turbo and equal length exhaust manifold may not be compatible.
