GreenFuchs | 10-row oil cooler with thermostat (+air deflector) | GT86 & BRZ I

GreenFuchs – 10-Row Oil Cooler with Thermostats (80°C & 90°C)

Efficient oil cooling for the highway/track, as well as demanding daily use

Technical Facts

• Solid 10-row aluminum cooler

• Interchangeable thermostats (80°C & 90°C) for precise temperature control (included in delivery, can be changed in 5 minutes). This allows you to switch between "Sport" (80°C for maximum early cooling) and "Daily" (90°C for later cooling to help the engine reach operating temperature) as needed for your specific use. Only available this way from us, because we know that "Toyubarus" rarely have just one purpose ;)

• 2 sensor ports (NPT 1/8) for analog oil temperature or oil pressure sensors (e.g., for P3 display; sensors not included)

• Two versions: with air duct plate or without – choose based on your requirements and installation position

Why air duct plates are crucial

Air duct plates optimize cooling performance by directing airflow specifically through the cooler channel instead of letting it simply pass by the sides. The result: oil temperature remains stable under high load (highway, cornering, mountain passes), even at slower speeds and in high ambient temperatures

Without such plates, a lot of air can escape without doing its job – the cooler works less efficiently, and the temperature rises unnecessarily .

Why this is important for your GT86/BRZ

Particularly in the FA20/FA24 boxer engine, oil temperatures of 110°C and above are common under high load – especially when using thin 0W-20 oil. Even 5W-30 only helps to a limited extent here. Exceeding the 120°C mark reduces viscosity and, consequently, lubricating performance – significantly increasing the risk of engine damage. Engine failures after long highway stretches or track sessions with high oil temperatures are excessively common in this model, highlighting the necessity of an oil cooler.

Advantages at a glance

1. Thermostat-controlled cooling – precisely prevents overcooling and provides effective protection

2. Air duct plate option – ensures defined airflow through the cooler – more effective at medium and high speeds

3. Sensor-ready – external ports compatible with P3 display & Co.

Recommendation

Whether for long highway trips, sporty backroad driving, or on the racetrack – anyone looking to keep their oil temperature in a safe range will find this to be an all-around high-quality system with a genuine impact on daily and sporting use.

Compatible oil filters:

Unfortunately, the OEM oil filter does not fit as its diameter is slightly too large. We recommend the HKS oil filter, which fits without issues. Alternatively, the STI oil filter also fits - GR and TRD filters unfortunately DO NOT.

You can find the installation instructions here for the Plus version with air duct plates and here for the Lite version without air duct plates.

Differences between Lite and Plus versions

The Lite and Plus versions use the same core components (sandwich plate, oil cooler, hoses, and fittings). The difference lies solely in the air duct plates and the mounting, which also affects the length of the hoses.

The Plus oil cooler is positioned on the far outside in front of the AC condenser and is mounted on the side and top. The Lite version, however, is connected somewhat more centrally and is mounted only from the top with a simpler bracket. Both variants are also compatible with other intakes, such as the Greddy air intake duct.
