The VR30DDTT motor is notorious for heat soak, especially of the intake air cooler system. After only a few pulls, the VR30 will aggressively reduce torque and boost in order to keep temps down, robbing you of horsepower. Nissan attempted to mitigate this issue with the second cooling pump on the Red Sport, but it's just not enough, especially in hotter climates. So CZP partnered with industry leader CSF to produce an upgraded intercooler heat exchanger to combat this issue!
The CZP Heat Exchanger more than triples the coolant capacity compared to the store core, and has more than double the front surface area! This increase in size dramatically improves cooling capacity for the water-to-air intercooler system, allowing you to drive harder and maintain maximum power output for longer!
