Koyorad: Alloy Radiator: NISSAN Armada Titan 04-06
Upgrade your Nissan Titan or Armada (2004–2015, compatible with Infiniti QX56) with the Koyorad HH-Series 48 mm Alloy Radiator (Part No. KH021687). Crafted with a high-density core and ultra-efficient fin design, this all-aluminum radiator offers 20–30% better heat dissipation than standard OEM units. Hand-built in Japan using TIG welding, Nocolok brazing, and heliarc quality standards, it ensures reliability, durability, and a polished finish. Designed for direct-fit installation, it retains factory hoses, mounts, fan shroud, and includes a billet filler neck and 1/8″ NPT sensor port—no modifications needed. Please note: this radiator does not include an internal transmission cooler, so an external trans cooler is required for automatic transmission models. Owners report much cooler running temps and an easy, seamless installation
