STM Evo 7/8/9 Standard Engine Oil Cooler Kit

STM Tuned Inc.



The STM Engine Oil Cooler Kit for Evo 7/8/9 is a direct bolt-on upgrade featuring a custom STM mounting bracket, B&M oil cooler and high-quality hose, fittings and hardware to attach to your factory oil filter housing for a clean and simple install.

If you purchased an older version of the STM kit and created your own bracketing solution, you can purchase just the STM Mounting Bracket. The STM brackets are different between the small (Standard) and large (Race) kits.

Vehicle Fitment:
2001-2006 Evolution VII VIII IX

Important Notes:
The fittings threading into the oil cooler are pipe thread. Over tightening pipe thread will cause things to break. If you are not familiar with it, please seek professional installation.
