THE IAG TRIPLE PASS COMPETITION SERIES 55MM RADIATOR
The IAG Triple Pass Competition Series 55mm Radiator is a high-performance aluminum radiator designed to work with 2002-2007 Subaru WRX and 2004-2007 STI models with the GD chassis. Engineered to cool more efficiently than the OEM radiator, this lightweight upgrade is perfect for competition applications and engines with performance modifications that have a tendency to run hot. The all-aluminum construction provides superior heat dissipation, ensuring your engine operates at optimal temperatures even under extreme conditions. IAG’s Triple Pass Competition Series 55mm Radiator is the perfect choice for enhanced cooling performance and reliability.
TRIPLE PASS DESIGN
The IAG Triple Pass Competition Series 55mm Radiator utilizes an advanced triple pass design, featuring baffles located inside 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, IAG’s innovative approach ensures the coolant stays inside the radiator longer, resulting in a significant increase in cooling efficiency. On average, the triple pass design improves cooling performance by 10-20% over the factory radiator, providing your engine with better thermal management even during intense performance scenarios.
ALUMINUM CONSTRUCTION
The Triple Pass Competition Series 55mm 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 circulates through the tubes. Additionally, aluminum offers exceptional resistance to corrosion, ensuring a long lifespan and reliable performance. The Triple Pass Competition Series 55mm Radiator is built to meet the demands of high-performance applications while providing efficient cooling and durability
FITMENT NOTES
