IAG Performance IAG Triple Pass Street Series 42mm Radiator for 2008-14 Subaru WRX , 08-21 STI

The IAG Street Series 42mm Triple-Pass Radiator is a high-performance aluminum radiator designed specifically for 2008-2014 Subaru WRX and 2008-2021 STI (GV/GR/VA chassis models). Engineered to cool more efficiently than the OEM radiator, this lightweight upgrade is perfect for heavy-use applications and engines with performance modifications that tend to run hotter. The all-aluminum construction provides superior heat dissipation, ensuring your engine remains at optimal temperatures even under extreme conditions. IAG’s Street Series Triple-Pass Radiator is the ideal choice for enhanced cooling performance and reliability. The IAG Street Series Radiator utilizes an advanced 3-pass design, featuring internal baffles within the end tanks that route the coolant through the radiator three times from inlet to outlet. Unlike the single-pass design of the OEM radiator, this innovative approach ensures the coolant stays inside the radiator longer, resulting in a significant increase in cooling efficiency. The IAG Triple-Pass Radiator is constructed from lightweight and durable aluminum, making it less likely to crack or bend even under high temperatures. Aluminum's excellent heat conductivity and rapid absorption properties allow the hot coolant to cool more quickly as it passes through the tubes. Additionally, aluminum offers superior resistance to corrosion, ensuring a long lifespan and reliable performance. The IAG Street Series 42mm Triple-Pass Radiator is made in the USA and built to endure the demands of high-performance applications while providing efficient cooling and durability.
