CSF 03-07 Infiniti G35 Radiator

When you're working on your 2003-2007 Infiniti G35, especially if it's seeing track time or has a high-horsepower build, keeping that engine cool is critical. This all-aluminum radiator from CSF is built to handle the extra heat. It's a direct replacement, meaning it fits right in without needing any modifications to your car's existing setup, and it accepts all your original mounting brackets, hoses, and fan shroud.

What sets this radiator apart is CSF's B-tube technology. Instead of standard oval tubes, these B-tubes are shaped to increase the heat transfer surface area by about 15% over regular tubes. This design allows for a dual liquid flow, essentially giving you the cooling efficiency of two smaller tubes in the space of one. Combined with ultra-efficient, multi-louvered fins that are precisely aligned to maximize airflow, this radiator is designed to reject heat effectively. The core is a 2-row, 42mm design, and the brackets and connections are CNC machined for a solid fit and durability. It even includes an all-aluminum race-style drain plug and a hand-polished mirror finish.
