Product Description

The **Koyorad HH020442 Racing Radiator** is a high-performance cooling upgrade engineered specifically for the **1994-1998 Nissan Skyline R33** and select **R34 (Non-GT-R)** models with manual transmissions and turbocharged or naturally aspirated inline-6 engines. With its robust 48 mm all-aluminum HH Series Hyper core, this radiator significantly increases coolant volume and heat dissipation compared to the original equipment unit, helping maintain stable engine temperatures under spirited driving, track days, or high ambient heat.

Built with precision Nocolok brazing and high-density fins, the radiator offers corrosion resistance and long service life. The direct bolt-in design utilizes stock mounting points and retains compatibility with factory fan shrouds and hoses for straightforward installation without modifications. An integrated accessory port allows for temperature sensor or gauge integration, making the HH020442 ideal for enthusiasts and tuners looking to improve cooling performance on classic Nissan Skyline performance platforms.
