CSF 18-23 Subaru Crosstrek / 17-22 Impreza High-Performance All-Radiator

The 42mm, 2-row aluminum core in this CSF radiator is designed to hold more coolant and dissipate heat more effectively than your stock unit. CSF's exclusive B-Tube technology is built into the cooling tubes, which can improve heat transfer by about 15% compared to standard oval welded tubes. Combined with super-efficient, multi-louvered fins that maximize airflow, this radiator is a solid choice for keeping your engine temperatures in check, especially during demanding activities like off-roading or overlanding where airflow might be limited.

When you're tackling steep inclines or carrying extra gear, your Subaru's 2.0L or 2.5L engine works harder, leading to higher operating temperatures that the factory radiator can struggle to manage. This CSF radiator offers a larger and more efficient core to combat those heat issues. Even when the radiator gets covered in dust or mud, the increased cooling capacity helps maintain optimal engine performance. The end tanks are constructed from high-grade aluminum and are TIG welded to the core for extra strength, a significant improvement over the weaker, crimped plastic end tanks found on OEM radiators, which are common failure points.

CSF designed this radiator as a true plug-and-play, drop-in fit for your Subaru Impreza or Crosstrek, meaning installation requires no modifications, trimming, or cutting. It's a direct replacement that fits right into your existing setup, ensuring a straightforward installation process. This all-aluminum radiator is individually leak and pressure tested before it leaves the factory, and it comes with a 2-year limited warranty for peace of mind.
