Perrin 2022 Subaru WRX Oil Cooler Kit

Aggressive driving, high RPMs, and turbocharged engines generate a tremendous amount of heat—especially in Subaru platforms known for their performance capabilities. Left unchecked, elevated oil temperatures can lead to reduced lubrication efficiency, accelerated engine wear, and ultimately, power loss or engine failure. The Perrin Oil Cooler Kit offers a serious upgrade for enthusiasts who push their cars to the limit on the street, track, or autocross course.

Designed with efficiency and reliability in mind, this kit features a high-capacity air-to-oil heat exchanger mounted directly behind the front bumper where airflow is most effective. The core is a precision-engineered Setrab unit, widely regarded as one of the most efficient and durable oil cooler cores in motorsport. Combined with lightweight, pre-assembled AN lines and a thermostatic sandwich plate, the system ensures your oil stays within optimal temperature ranges—improving both performance and engine longevity.

The thermostatic plate opens only when oil temps reach operating range, which means you won’t overcool the oil on cold starts or during mild driving. All fittings and hoses are pre-assembled and pressure tested, making installation smooth and stress-free. And yes—it’s a noticeable upgrade. Expect cooler running temps under sustained load, improved engine consistency lap after lap, and peace of mind knowing you’re protecting your investment.
