CSF High-Performance Aluminum Radiator - Fits 2005-2009 Subaru Outback / Legacy

The 42mm 2-Row aluminum core not only increases the fluid capacity of the radiator, but also improves the cores ability to dissipate heat. CSF’s Exclusive B-Tube Technology improves heat transfer by approximately 15% over regular oval welded tubes. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible performance.

Efficiency is key in off-roading as speeds tend to be lower overall so you end up relying on the fans to move most of the air over the radiator. While the factory fans do a decent job pulling air through the radiator core, it is still less airflow than you’d typically see in city driving. A larger and more efficient core will keep your engine temps in check and keep your engine running strong. Also, a larger core also helps when your radiator is covered in dust, dirt, or mud. While a radiator isn’t functioning at peak efficiency in there situations, the more overall cooling capacity you have the better.

This radiator fits the manual transmission models only! It can work on the Automatic Transmission models if you get an external transmission cooler along with this radiator. We recommend this Mishimoto Transmission Cooler for automatic transmission models.
