The AAM Competition R-Line Oil Cooler System is the best, most effective oil cooling system for the 370Z. Designed to ensure peak performance under the most extreme driving conditions, the extremely efficient Oil to Water cooling core effectively reduces the overall engine temperature greatly aiding engine reliability. The AAM Competition R-Line Oil Cooler System is proven to drop oil temperatures by an astonishing 40-90 degrees Fahrenheit! All other aftermarket oil coolers available for the 370Z use a air-to-air cooling cores which are mounted in front of the radiator in the front bumper fascia, blocking air flow to the radiator. The AAM Competition R-Line Oil Cooler system does not block airflow to the radiator as it can be mounted out of the way, also making it prefect for forced induction (turbocharged/supercharged) applications as it does not mount in the way of the intercooler. Whether you’re on the street or at the track, the R-Line Oil Cooler Kit has you covered.
