What makes CSF's B-Tube Technology different from standard radiator tubes?

CSF's B-tubes are specially engineered with a unique shape that increases the heat transfer surface area by about 15% compared to regular oval tubes. This design allows for a dual liquid laminar flow, leading to more efficient heat dissipation.

Do I need any special tools or modifications to install this radiator?

No, this radiator is designed as a direct, drop-in fit. It requires no modifications for installation, and the inlet/outlet connections are made to match the OE specifications, allowing you to reuse your original hoses.

Can I use my existing AC condenser and fan shroud with this CSF radiator?

Yes, this CSF radiator is designed to accept your OEM AC condenser and fan shroud, ensuring that essential components can be reused during installation.

Product Details

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 Porsche 991.2 Carrera, GT3, GT2, or 718 Boxster/Cayman running at its best, especially if you've added horsepower or plan on hitting the track, a CSF high-performance radiator is a smart choice. This is the right-side radiator, designed to be a direct replacement.

What sets this radiator apart is its construction. It features a 2-row, 42mm core that uses CSF's exclusive B-Tube Technology. Instead of a standard oval tube, these B-tubes are shaped to increase the heat transfer surface area by about 15% over regular tubes, giving you the efficiency of two smaller tubes in the same space. This design also allows for a dual liquid laminar flow, which helps dissipate heat more effectively. The radiator also uses multi-louvered fins that are precisely aligned to maximize airflow, and CSF tests these designs in a wind tunnel to ensure maximum heat rejection efficiency.

You won't have to worry about complicated installation. This radiator is a true drop-in fit, meaning it requires no modifications to install. The brackets and fittings are CNC machined for durability and a precise fit, and the inlet and outlet connections are designed to match the original equipment, so you can reuse your factory hoses. It's also designed to accept your OEM AC condenser and fan shroud.
