Oil Cooler Kit for Subaru BRZ (2013-2019) 2.0L

Thermostatic Oil Cooler Kit for 2013-2019 Subaru BRZ (ZC6)

What it Does: The thermostatic oil cooler kit adds an external 19-row heat exchanger to the 2013-2019 Subaru BRZ to regulate operating temperatures and prevent thermal oil breakdown under sustained load.

The Stock Subaru BRZ Thermal Limitation

The factory FA20 engine in the ZC6 chassis lacks a dedicated air-to-oil cooler, relying on passive dissipation that quickly proves inadequate during aggressive driving or track events. Oil temperatures frequently exceed 260°F (127°C), causing standard motor oil to experience severe viscosity breakdown and thermal shearing. This drop in hydrodynamic film strength accelerates rod bearing wear, compromises camshaft journal lubrication, and risks catastrophic bottom-end engine failure.

The Engineering Solution

Engineered for maximum thermal dissipation, this direct-fit system utilizes a 19-row aluminum bar-and-plate core engineered to withstand high vibration and track-duty hydraulic pressures. An integrated 73°C (163°F) thermostatic sandwich plate bypasses the cooler core during initial operation to maintain fast engine warm-up, only opening fluid passages once operating threshold is reached. Paired with high-pressure reinforced lines and leak-free adapter fittings, this system stabilizes oil viscosity, preserves critical bearing clearances, and protects internal components during sustained high-rpm use.

What's Included

• 19-row aluminum oil cooler
• 73°C thermostatic sandwich plate with spacer
• 2 x high-pressure oil hoses
• Mounting bracket and installation fittings

Frequently Asked Questions & Fitment Warnings

Does this fit the ZC6 BRZ?

Yes, this is a direct fit for the 2013-2019 Subaru BRZ equipped with the FA20 2.0L engine.

Will this system cause engine overcooling during street driving?

No, the integrated 73°C thermostatic sandwich plate prevents flow to the external core until engine oil reaches proper operating temperature.
