Mishimoto MMRAD-STI-08 Performance Aluminum Radiator, Compatible with Subaru Impreza WRX & STI, 2008-2019

Compatible with Subaru WRX or STI (2008–2019), the Mishimoto MMRAD‑STI‑08 performance aluminium radiator is engineered to deliver advanced cooling, reliable construction, and standout engine bay visuals. With a robust all‑aluminium build and a core that provides up to 30% better cooling efficiency compared to OEM units, this radiator is essential for high‑performance driving, track use, or hot weather conditions. Crafted from aircraft‑grade 100% brazed aluminium, it features TIG‑welded end tanks and a sturdy magnetic drain plug to collect metallic debris. A high‑pressure radiator cap allows coolant to flow more efficiently at higher boiling points, while the polished finish and clean welds enhance the look under your hood. A thicker core increases cooling surface area and thermal mass, consistently maintaining coolant temperatures about 10 °F lower under demanding road or track conditions. Upgrading to this radiator helps minimise overheating risks, aligns with motorsport trends, and contributes to long‑term engine longevity. Since 2005, Mishimoto has led performance cooling innovation, focusing on engineering reliability through dyno testing and real‑world validation. This radiator reinforces that legacy with durable materials, precise manufacturing, and optimised cooling performance to keep your Subaru running strong.
