TR Temperature Controlled Oil Cooler Kit for 2015+ Subaru WRX

Keep your FA20 happy on street and track. The Tomioka Racing Temperature-Controlled Oil Cooler Kit is engineered for the 2015–2021 Subaru WRX (FA20DIT) to stabilize oil temps, preserve viscosity under boost, and add confidence on spirited drives, canyon runs, and HPDE days. Why it works Thermostatic control (~180°F start-to-open): OEM-like warm-up, then automatic routing through the cooler as temps rise (fully open ~190–195°F). High-efficiency stacked-plate core: Excellent heat rejection with low pressure drop when paired with the included -AN lines. Vehicle-specific brackets: Clean, repeatable fitment and reliable airflow to the core. Motorsport-grade plumbing: Heat- and oil-resistant lines and swivel fittings simplify routing and service. Real-world benefits More stable oil temps: Helps prevent heat-soak spikes during back-to-back pulls and long climbs. Protects bearings & turbo: Keeps viscosity in the sweet spot so the FA20 can take abuse without breaking a sweat. Dail
