370Z HKS A/T Cooler Kit – 27002-AN001

【A/T FLUID COOLER KIT】
Proper Fluid Temperature Management to Enjoy Driving.
Rough driving of automatic cars raises the AT fluid temperature. Excessive AT fluid temperature decreases the fluid viscosity which may cause abrasion to the built-in disk and/or brake. HKS A/T Fluid Cooler can reduce the oil temperature while maintaining the automatic transmission performance of tuned vehicles.
