If you're serious about keeping your 350Z running cool, you really can't go wrong with the CSF High-Performance All-Aluminum Radiator. With over 50 years under their belt, CSF knows a thing or two about radiators, and this one is no exception. Whether you’re tearing up the streets or hitting the track, this radiator is built to handle the heat, especially if you’ve got a high horsepower setup or just want to ensure your ride stays cool in those intense motorsport situations. What sets this radiator apart? For starters, it features a 2-row core design that utilizes CSF's exclusive B-Tube Technology. Instead of the standard oval "O" shape, these tubes are shaped like a "B"—and trust me, it makes a difference. This unique design allows for a thinner and lighter aluminum construction while actually being stronger than traditional tubes. You get better cooling efficiency without the extra weight. Plus, the B-tube design increases the heat transfer surface area by about 15% compared to regular tubes. It's like having the efficiency of two smaller tubes packed into one, which is a game changer when you're pushing your engine hard. The radiator also boasts ultra-efficient multi-louvered fins that are meticulously aligned to maximize airflow. CSF didn’t just throw this together; they’ve tested the fin specifications in wind-tunnel labs to ensure you get the best heat rejection possible. And the best part? It’s a drop-in fit, so you won’t be spending your Saturday afternoon wrestling with modifications. Just pull out the old one and slip this beauty in using the OE-style brackets that are CNC machined and welded for durability. You can reuse your OEM hoses or aftermarket ones since the inlet and outlet connections match the original setup. It’s all about making your life easier while ensuring your engine stays cool under pressure. Plus, it comes with a polished finish that not only looks good but also means it’s ready to perform right out of the box. So if you're looking to upgrade your cooling system, this CSF radiator is seriously worth considering. It’s built for performance and reliability, and you can trust that it’s going to keep your 350Z running at its best, no matter where the road takes you.

Take care of your radiator, as under circumstances listed below the warranty will be void.

If the radiator is installed and is returned deformed (bulging tanks, warped core etc.), this is an indication that the radiator is the victim of some other problem and not the cause. The deformation is a result of the radiator being subjected to extremely high pressure and or temperature caused by any of the following reasons:Defective Pressure Cap, Defective Head Gasket, Defective Temperature gauge (incorrect readings), Defective Water Pump etc. Such units are not covered under the warranty.

If a radiator seems to have a “fit problem” there is the possibility that there is some confusion about a multi-fit radiator that might look different. Your nearest CSF WD can clarify the application, just give them a call. A perceived fit problem is not covered under warranty.

If a unit is damaged in shipping, please file a claim with the carrier. Damages caused during shipping, installation or handling are not covered under warranty.
