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. In Addition, the end tanks are made from high grade aluminum and TIG welded to the core for extra strength. In contrast, the OEM crimped onto plastic end tank design is much weaker and creates a weak point where failure is more likely. Because the CSF radiator is designed as a true plug-and-play drop-in fit application, installation requires absolutely no modifications, trimming, or cutting.. The stout 2.0L (FB20) and 2.5L (FB25) naturally aspirated motors are more than up for the task of off-roading and overlanding. However, those activities can be a lot harder on it than you might expect. Between dealing with traction loss, steep inclines, and additional weight of gear, there is almost always more strain on the engine. The result is above average operating temperatures that the factory radiator can struggle to keep up with. That's why CSF developed this High-Performance All-Aluminum Radiator for the Crosstrek and Impreza.. The CSF #7216 Cooling product is designed to be a "Drop-In Fit" application.
