IAG 42MM TRIPLE PASS STREET SERIES RADIATOR FOR 08-14 WRX & 08-21 STI
THE IAG STREET SERIES TRIPLE PASS RADIATOR
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.
TRIPLE PASS DESIGN
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. On average, the 3-pass design improves cooling performance by 10-20% over stock, providing your engine with better thermal management even during intense performance scenarios.

ALUMINUM CONSTRUCTION
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.
FITMENT NOTES
The Street Series Radiator features a 42mm (1.654”) core and is designed to work seamlessly with OEM radiator fans using the original mounting positions. The lower radiator outlet remains in the stock location, utilizing the original lower hose. The upper radiator inlet has been relocated and requires the included IAG 4 Ply Silicone Upper Radiator Hose (Part #IAG-ENG-2304) for installation. A -6 AN Male Fitting is welded on one end for applications that need a coolant expansion tank. For applications that do not require this fitting, a -6 AN female cap is included.
