CSF 00-10 Honda S2000 Radiator

CSF has been making radiators for over 50 years, so they know a thing or two about keeping engines cool. If you're looking to keep your 2000-2009 Honda S2000 running at its best, especially if you've added more power or plan on hitting the track, a high-performance radiator like this one from CSF is a smart move. It's built to handle the extra heat that comes with performance driving.

This radiator uses CSF's unique "B-Tube" technology. Instead of a standard oval shape, these tubes are formed into a "B" shape and then brazed. This design is stronger, allowing CSF to use thinner, lighter aluminum while still getting better cooling efficiency. The "B-tubes" increase the surface area for heat transfer by about 15% compared to regular tubes, giving you the cooling effect of two smaller tubes in the space of one. CSF also uses precisely aligned, multi-louvered fins that are tested in a wind tunnel to maximize airflow and heat rejection.

You'll find that this radiator is designed as a direct fit for your S2000, meaning it bolts right in without needing any modifications. It uses OE-style brackets that are CNC machined for durability, and the inlet and outlet connections are made to match your factory hoses, so you can reuse your original equipment or aftermarket ones. It even accepts all the original mounting hardware, including the AC condenser and fan shroud.
