The AMS EVO X MR/Ralliart SST Transmission oil cooler kit is the first of its kind for the SST transmission. Many SST owners know all too well the problems plagued with the 6 speed dual clutch automatic transmission in the EVO X MR and Ralliart. Overheating is a common occurrence when driven hard. The AMS Trans. cooler helps to prevent that by using a high quality larger capacity heat exchanger with a fan that pulls air through the core the entire time the car is running. This helps to keep transmission temperatures in check and keep that pesky “slow down” light on the dash from coming on so often.


  • Full time fan to constantly pull in air through the cooler
  • Directly replaces the OEM cooler, no cutting or modifying OEM plastics or body panels
  • High quality oil cooler that adds an extra ½ quart of fluid capacity
  • Large frontal area of core allows for even better cooling

Kit Includes

  • One of the best oil coolers on the market
  • Electric fan that easily wires into the factory fuse box
  • Stainless steel brackets for long life and a seamless install
  • All necessary hardware and wiring to install in the OEM location and to OEM lines


  • Oil cooler capable of holding .5 additional quarts
  • High quality 8” fan with stainless steel shroud
  • 100% Stainless steel brackets
  • Aeroquip push-lock fitting for OEM hose integration


  • Mitsubishi Lancer Evolution 10 MR
  • 2009+ Lancer Ralliart with SST Transmissions

Product Note

  • Due to the size of the transmission cooler being much larger than stock most aftermarket lower intercooler pipes will not fit, including the AMS lower intercooler pipe. This kit is made to fit with the stock intercooler pipe.
