CSF Nissan 350Z (DE Engine) 2003-2006 High-Performance Radiator

CSF has over 5 decades of experience manufacturing radiators, so when it comes to keeping your engine cool and your 350Z running at its best, a CSF High-Performance All-Aluminum Radiator is the obvious choice. Designed to perform on the street or at the track, a performance radiator is a must-have for both high-horsepower builds and race vehicles needing added cooling performance in motorsport environments.

The 2-row, 42mm dual core uses CSF's exclusive B-Tube technology. Rather than a regular oval "O"-shaped tube, CSF uses a specially engineered tube shaped like a "B", carefully formed and brazed over the seam to seal. This increases the heat transfer surface area of the tubes by approximately 15% over regular tubes, delivering the efficiency of two smaller tubes versus one large tube within the same space, and allows CSF to use thinner, lighter aluminium with better cooling efficiency, since this design is actually stronger than normal welded "O"-shaped tubes. High-efficiency, multi-louvered fins with a 6.5mm fin height are precisely aligned and wind-tunnel tested for maximum heat rejection efficiency. This is a true drop-in fit design requiring no modifications to install, with OE-style brackets all CNC machined and welded for genuine durability, and inlet/outlet connections designed to match the OE connections so you can reuse factory or aftermarket hoses.

Works with: OEM mounting points and hose connections, specific to VQ35DE-equipped models. Fits both manual and automatic transmission.
