Tomei Oil Thermostat Killer For Mitsubishi EVO 4-10 4G63/4B11

We are one of Tomei authorized dealers - Kure International, Inc., Please shop with confidence.

Model: Lancer Evolution Evo 4-9 and Evolution 10

Engine: 4G63 / 4B11

Description:

One of the seldom-weak points of the 4G63 / 4B11 is the rise in oil temperature. It is seen more often in circuit driving.
The EVO uses a thermo switch that will work when the temperature gets around 85C (approx 185F).
Yet when the oil temp is low, it will restrict the oil flow to the oil cooler constantly regardless of the temperature.
Still it is easy to revert back to the OEM switch for winter use to prevent over cooling.
