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

STM Tuned Inc.


Vehicle Fitment:
2001-2006 Mitsubishi Lancer 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.

The Engine Oil Cooler Kit for the 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.

• Easy to bolt in to factory location
• Strong, laser-cut, tig-welded and powder coated bracket
• Includes everything needed to install
• Nylon-covered stainless braided hose won't scratch finishes
• Low-profile 90° fittings for the oil cooler

Stm is second to none

This was just one out of the 20 something other things I ordered. Stm got everything to my door super quick. Connor was even kind enough to help out with some issues as well as provide me pictures and instructions on how to install a part.
