HKS - Transfer Case Oil Cooler Kit – 2023+ Toyota GR Corolla (GZEA14H)

Enhance the AWD drivetrain reliability of your 2023+ Toyota GR Corolla with the HKS Transfer Case Oil Cooler Kit, engineered to dramatically improve thermal management under high-load conditions. Designed specifically for the GZEA14H platform, this kit helps prevent overheating of the transfer case during aggressive driving, track events, or extended spirited use — a known weak point when the GR Corolla is pushed hard.

The HKS cooler setup increases fluid capacity and circulates oil through an external heat exchanger to stabilize temperatures and maintain consistent viscosity. This translates into better power delivery, reduced drivetrain stress, and longer component life.

Ideal for tuned, canyon-driven, or track-prepped GR Corollas, this kit ensures your AWD system performs consistently even in high-heat environments.

Key Features

Why This Upgrade Matters

The GR Corolla’s AWD system is powerful but generates substantial heat during high-load driving. The HKS Transfer Case Oil Cooler Kit directly addresses this by delivering professional-grade thermal management—keeping the drivetrain cooler, more consistent, and ready for long-term reliability.
