CSF 02-07 Subaru Impreza Radiator

When you're working on your 2002-2007 Subaru Impreza, especially if it's a WRX or STI model, keeping that engine cool is a top priority. This all-aluminum radiator from CSF is built to handle the demands of both street driving and track use, making it a solid choice for anyone looking to improve their cooling system's performance. It's designed as a direct replacement, meaning it fits right in without needing any modifications to your car.

What sets this radiator apart is CSF's B-Tube technology. Instead of a standard oval shape, these tubes are engineered with a 'B' shape that increases the heat transfer surface area by about 15% compared to regular tubes. This design is also stronger, allowing CSF to use thinner, lighter aluminum while still achieving excellent cooling efficiency. The core also features multi-louvered fins that are precisely aligned to maximize airflow, ensuring heat is dissipated effectively. The brackets and fittings are CNC machined for a durable, precise fit, and the inlet and outlet connections are made to match the factory setup, so you can reuse your original hoses.

This radiator includes the radiator itself and an all-aluminum race-style drain plug for easy fluid changes. It's a well-built component designed to help your Impreza run at its best, whether you're dealing with a high-horsepower build or just want added peace of mind during spirited driving.
