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.
