Perrin Performance [15-21 Subaru WRX] Oil Cooler Tuner Kit

PERRIN Oil Cooler Tuner Kit for 2015‑2021 WRX is an engine oil cooling core and bracket set designed for Subaru WRX models from 2015 through 2021, enabling custom hose and fitting configurations for tailored builds.

• High-efficiency bar and plate oil cooler core maximizes heat dissipation while maintaining oil flow and pressure.
• Includes two 304 stainless steel mounting brackets engineered for secure front-mount installation.
• Core dimensions: 9.5" x 4.75" x 2.2"; designed to handle substantial heat loads with a BTU/hr range of ~22,000–29,000.
• Core delta pressure rating around 3.0–3.5 PSI helps maintain system balance.
• Requires approximately 1 quart of additional engine oil when installed.
• Tuner-kit format provides flexibility — hoses and fittings are not included, so the installer chooses components to match specific performance or racing setups.

This kit is suited to builds where maintaining lower oil temperatures under sustained high RPM or track use is a priority, helping to support consistent lubrication and potentially extending engine life.
