You must have this item if you are driving Z34 at a circuit, because when you are driving, the oil temperature will rise and the fail-safe system will be turned on.

Features When driving the Z34 and the engine oil temperature goes above 135℃ (130℃), the fail-safe will limit the throttle duration and the max RPM. But this kit will prevent the fail-safe system to activate. 15 rows core (W200 X H220 X T48) is in front of the radiator. For installation of the kit you need parts modification of resin protector and alternator bracket. Installation requires approximately 3 hours.

Characteristic At the Fuji Speedway test drive with the stock, we couldn't even go for one lap because of the fail-safe, but with the HKS Oil Cooler Kit installed we could go for 6 laps. * We recommend the twin core kit for long run at the circuit.
