Upgrade your 2004-2008 Mazda RX-8 cooling system with the Koyorad V-Series 36mm Radiator featuring a built-in oil cooler (KOYO-KV061616R / KOYO-V2695). Perfect for RX-8 owners who need a compact radiator with enhanced oil cooling, this unit combines space-saving design with high-performance durability.

With OE-specific mounting points and a precision-machined billet filler neck, installation is simple, requiring no modifications or custom fittings.
