CZP by CSF Oil Cooler Kit - Nissan Z 2023+ RZ34

If you've ever had the opportunity to track your new Z, you know the oil temperatures get way too high! We have seen temps exceeding 270°F while full-out on the track. Nissan's V6 engines have become notorious for high oil temperatures over the years, usually just resulting in the ECU limiting power, but this can cause harmful engine damage if these extreme temperatures are sustained. This is especially true for the VR30 since it uses such thin oil to begin with. We teamed up with industry leader CSF to produce a cooler that not only is thicker than stock, but also has a larger surface area, and retains the factory V-mounted design. The kit comes complete with brackets, hoses and a custom molded air duct to vent the hot exhausted air down and out under the car, keeping engine bay temps low. This is the best way to keep oil temps under control in your 2023+ Nissan Z!




We tested both the stock oil cooler and the CZP oil cooler on a closed track, with a fresh oil change done prior to each run to try to show the difference in how oil temperatures are handled between the two coolers. The stock cooler simply cant handle high RPMs under a sustained load for more than 10 minutes of driving without getting to dangerously high temperatures, while the CZP cooler settled to a lower maximum temperature sooner and holds it steady.

Why does oil temp matter?

The Arrhenius Rate Rule states that with every increase of 10°C in a lubricant's base temperature, oil life is halved. This means the higher temps your oil reaches, the less effective it is at doing its job. More carbonaceous deposits, reduced oil films, and additives breaking down rendering even high end oils ineffective at reducing engine wear after exposed to high temps. The result is simple and indisputable: high oil temperature leads to engine wear and damage. Don't let your track times and engine life be held back by the undersized stock cooler!
