IAG Triple Pass Competition Series 55mm Radiator, 2015-2021 WRX

The IAG Triple Pass Competition Series 55mm Radiator is a high-performance aluminum radiator engineered for 2015-2021 Subaru WRX models. Designed to deliver significantly improved cooling over the OEM radiator this lightweight upgrade is ideal for competition use and performance-modified engines that generate higher operating temperatures. Its all-aluminum construction promotes excellent heat dissipation helping maintain optimal engine temperatures even under extreme conditions. IAG's Triple Pass Competition Series 55mm Radiator is the perfect solution for enhanced cooling performance and reliability. The IAG Triple Pass Competition Series 55mm Radiator features an advanced triple-pass design with internal baffles in the end tanks that direct coolant through the radiator core three times from inlet to outlet. Compared to the OEM single-pass radiator this design increases coolant dwell time within the radiator resulting in a significant gain in cooling efficiency. On average the triple-pass configuration improves cooling performance by 10-20% over the factory radiator delivering improved thermal management even during high-demand driving conditions.
