If you're looking to keep your Porsche 911 Carrera running cool, you can't go wrong with the CSF High-Performance All-Aluminum Radiator. With over 50 years in the game, CSF knows a thing or two about radiators, and this one is built to handle whatever you throw at it—whether that's a spirited Sunday drive or a full-on track day.

This radiator features a 2-row core with CSF's unique B-Tube Technology. Now, what’s the deal with the B-tubes? Unlike the standard oval-shaped tubes you usually see, these are shaped like a "B," which means they’re not just lighter but also stronger. This design allows for thinner aluminum that cools better. It increases the heat transfer surface area by about 15% compared to regular tubes, giving you the efficiency of two smaller tubes in the same space as one big one. Pretty neat, right?

And let’s talk airflow. CSF’s got you covered with ultra-efficient, multi-louvered fins that are precisely aligned to maximize airflow through the radiator core. Each fin is measured and tested for optimal heat rejection in their wind-tunnel lab. You’re getting a radiator that’s not just a pretty face; it’s built to perform.

What’s great about this radiator is that it’s a true drop-in fit. You won’t need to modify anything to get it installed. The OE-style brackets are CNC machined and welded for durability, and the inlet and outlet connections match up with your stock hoses, so you can stick with OEM or aftermarket options without a hitch.

Here are some specs to chew on:

  • 2-Row 42mm Core with B-Tube Technology (+20% Efficiency)
  • Core Height: 14.25 in., Thickness: 1.625 in., Width: 14.3125 in.
  • Inlet Diameter: 1.375 in. (Top Right), Outlet Diameter: 1.375 & 1.125 in. (Bottom Left)
  • All-Aluminum Design with 100% TIG-Welded End Tanks
  • Installation is a breeze—just drop it in with no modifications needed

This radiator is a solid upgrade whether you're racing, hitting the streets, or just need a reliable replacement. It also accepts the OEM AC condenser and fan shroud, so you can keep your car's interior cool while your engine stays chill.

Compatible with:

  • Porsche 991.1 GT3/GT3 RS (2014-2016)
  • Porsche 991.1 Turbo (2014-2016)
  • Porsche 991.2 Carrera (2017)
  • Porsche 991.2 Turbo (2017-2019)
  • Porsche 997.2 Turbo (2013)

So, if you want to keep your 911 running at its best, this radiator from CSF is a no-brainer. Trust me, your engine will thank you.
