A direct replacement for the standard part, Direnza radiators feature twin-core technology for optimised cooling capability. Constructed from aircraft grade aluminium (a material well-known for its excellent thermal conductivity), our radiators are the perfect addition to any car, including those driven hard on track.
Designed and developed in-house by Direnza engineers, our radiators provide as much as 40% additional cooling capacity compared with standard radiator systems, their robust yet intricate design, and exceptional cooling performance a testament to our R&D processes.
Direnza radiators are TIG-welded for additional strength and durability. TIG welding also provides a more precise finish than MIG welding, and reduces stress on the material at hand. Our radiators will enhance the appearance of any engine bay.
