Description
The Perrin Front Mount Intercooler Core is a precision-engineered upgrade designed specifically for Subaru WRX and WRX STI models spanning 2002 through 2025. This intercooler core enhances charge air cooling efficiency by maximizing airflow and minimizing pressure drop, making it an ideal choice for enthusiasts seeking reliable power gains without compromising daily drivability. Whether you’re running a stock turbo setup or have moderate bolt-ons, this intercooler core supports improved performance and consistent boost delivery.
Built with a robust 3/8” bar and plate design, the Perrin intercooler core offers superior durability compared to traditional tube and fin cores. Its dimensions—28 inches long, 9.25 inches tall, and 3.5 inches deep—are optimized to fill the entire front bumper opening, ensuring maximum exposure to ambient airflow. The end tanks feature a smooth taper that eliminates turbulence and evenly distributes hot charge air across the core, enhancing cooling efficiency and reducing heat soak during spirited driving or track sessions.
Real-world benefits include a dyno-proven increase of 10 to 20+ wheel horsepower thanks to cooler intake air temperatures and reduced boost pressure losses. The core is pressure tested to 50 psi to guarantee leak-free operation, preserving turbocharger efficiency and engine response. Best of all, this intercooler core requires no ECU tuning for safe installation, allowing Subaru owners to enjoy immediate gains with the option to unlock even more power through custom tuning.
