STILLEN designed this Heavy Duty Steering Fluid Cooler to handle driving habits ranging from casual cruising to extreme canyon running. If you are auto-crossing, doing some extreme driving, or have swapped your wheels & tires for a wider and larger diameter set, you are taxing your stock steering fluid cooler and risking the chance of boil-over or cooking the fluid.
The differences between the stock steering Fluid Cooler and the New STILLEN unit are capacity and volume. The reservoir for the STILLEN unit is larger which eliminates the chance of boil-over. The lines are also larger in diameter, allowing more volume through the steering system.
On the 350Z, this kit uses the stock mounting locations. On the G35 Coupe, installation will require the drilling of mounting holes to fit the kit on the vehicle. The stock mounting position on G35 Coupe can not be utilized because of varying stock mounting points due to slight changes between different production dates. Instructions are included. This kit will fit the 350Z and G35 Coupe, both 6-Speed and Auto.
