Engineered to deliver improved cooling over the OEM radiator this lightweight upgrade is a solid choice for heavy-use applications and performance-modified engines that generate more heat. Its all-aluminum construction offers excellent heat dissipation helping maintain stable engine temperatures even under demanding conditions. The IAG Triple Pass Street Series 42mm Radiator is an ideal solution for increased cooling efficiency and long-term reliability.
