HKS Oil Cooler Kit Toyota GR Yaris (GXPA16)

The HKS Oil Cooler Kit for the GR Yaris GXPA16 provides the oil temperature control needed for high-power and continuous track use. The factory system struggles with chronic high oil temperatures. This kit stabilises temperatures, protects the engine, and allows longer, more consistent performance during hard driving.

Product Overview

This kit uses a Turn-Flow Type oil cooler core, a billet aluminium sandwich plate, and AN10 oil lines for efficient cooling in limited space. The layout manages both oil temperature and water temperature, ensuring the engine remains stable under extended load. The cooler is designed for vehicles with increased output and repeated high-RPM operation.

Kit Includes

• Oil Cooler Core
• Billet Aluminium Sandwich Plate
• Oil Cooler Pipes
• AN10 Oil Cooler Hoses

Key Features

• Improves oil temperature control for tuned and high-power GR Yaris vehicles
• Supports multiple continuous laps without overheating
• Turn-Flow Type core provides efficient cooling with a compact footprint
• Aluminium pipes maximise flow efficiency in tight engine bay space
• Designed for both oil and water temperature stability

HKS Track Test Data

• Track: Fuji Speedway Short Course
• Ambient Temp: 25°C
• Vehicle used with HKS suspension, intake, intercooler, muffler, and 0W-20 HKS oil

Testing showed significantly lower oil temperatures, allowing roughly four times more driving time compared to stock before reaching critical temperature levels. This confirms the kit’s ability to maintain stable oil conditions under real track conditions.

Description

HKS found that the GR Yaris is highly prone to rising oil temperatures during prolonged use. This Turn-Flow Type cooler was developed to address those conditions and maintain performance during circuit driving. Real-vehicle testing confirmed stable oil temperatures and reliable output for extended sessions.
