Performance Overview:

Aggressive driving, autocross events, canyon runs, and wider wheel and tire setups place significantly more load on the factory power steering cooling system. Under these conditions, the stock steering fluid cooler can become overwhelmed, leading to fluid overheating, boil-over, and degraded steering performance.

The STILLEN Power Steering Cooler Kit addresses these issues by increasing both fluid capacity and system volume. The larger reservoir design reduces the risk of overheating, while larger-diameter fluid lines allow increased flow through the steering system, improving overall cooling efficiency and reliability.

Design & Installation Details:

The STILLEN power steering cooler features a heavy-duty construction designed to withstand sustained high temperatures and demanding driving conditions. All fittings and hoses are pre-installed for a clean, reliable installation.

• On Nissan 370Z models, the kit utilizes factory mounting locations for straightforward installation
• On Infiniti G37 Coupe, Q40, and Q60 Coupe models, drilling mounting holes is required due to variations in factory mounting points between production years

Installation instructions are included to ensure proper fitment and secure mounting.

Transmission Compatibility:

• Fits both 6-speed manual and automatic transmission vehicles

The STILLEN Power Steering Cooler Kit [400736] is an essential upgrade for drivers pushing their Nissan 370Z or Infiniti G-series platform beyond factory limits, ensuring reliable steering performance and protection against fluid overheating during spirited driving.
