What makes CSF's B-tube technology different from standard radiator tubes?

CSF's B-tubes are shaped to increase heat transfer surface area by approximately 15% compared to standard oval tubes. This design allows for a dual liquid laminar flow, enhancing cooling efficiency.

Does this radiator require any modifications to install on my Porsche 911?

No, this CSF radiator is designed as a true 'drop-in fit' and requires no modifications for installation. It uses OE-style connections and accepts the factory AC condenser and fan shroud.

What is the expected lifespan or warranty for this radiator?

CSF has over 5 decades of experience manufacturing radiators. While specific warranty details are not provided, each CSF radiator is individually leak and pressure tested before shipment.

Product Details

This CSF radiator uses an all-aluminum construction with a 42mm, 2-row core featuring CSF's exclusive B-tube technology. Unlike standard oval tubes, these B-tubes are seam-brazed and shaped to increase the heat transfer surface area by about 15%, effectively acting like two smaller tubes in the same space. This design allows for a dual liquid laminar flow, which CSF states increases efficiency by up to 20% over standard tubes. The radiator also incorporates multi-louvered fins with a 6.5mm height, precisely aligned to maximize airflow and heat rejection, a specification tested in CSF's wind-tunnel lab.

Engineered as a direct, drop-in fit for your 2001-2005 or 2007-2012 Porsche 911 Turbo, GT2, or GT3, this radiator requires no modifications for installation. The OE-style brackets are CNC machined and welded for solid durability, and the inlet and outlet connections are designed to match the factory specifications, allowing you to reuse your original hoses. This radiator is well-suited for high-horsepower builds, track use, or simply as a high-performance upgrade over the stock unit, ensuring your engine stays cool under demanding conditions. It's also designed to accept the OEM AC condenser and fan shroud.

Each CSF radiator is individually leak and pressure tested before it leaves the factory, and this unit features a smooth satin finish. Trust CSF's over 50 years of experience in cooling system manufacturing to keep your Porsche running at its best.
