If you're looking to keep your engine cool under pressure, the CSF radiator is where it's at. I've been around the block with various radiators, and let me tell you, CSF knows what they're doing. They’ve got a lineup that covers over 3,200 applications, so whether you’re rolling in an Acura or a Volkswagen, they’ve got you sorted. And trust me, when it comes to materials, they don’t skimp. Whether your setup is Copper-Brass, Plastic-Copper-Brass, Plastic-Aluminum, or All Aluminum, CSF matches the OEM style and quality, which is a big deal for us who care about the details.

What I really appreciate about CSF is their commitment to quality. These aren’t just any radiators; they’re built to last with some serious engineering behind them. With over 50 years in the game and more than 30 million units sold worldwide, you know they’ve got a reputation to uphold. Each radiator is wind tunnel tested to validate cooling performance, which is a fancy way of saying they really put these things through their paces before they hit the market.

The construction is top-notch too. You’ve got OEM specified Plastic Tank-Aluminum Core construction, which means it’s designed to take a beating. The tanks are made from virgin grade engineered plastic resins that are glass-filled for added strength and durability. Plus, the gaskets are made from special grade EPDM rubber, so they can handle extreme temperatures—up to -120 degrees Fahrenheit. That’s some serious heat resistance!

Now, let’s talk features. The fins are where the magic happens, and CSF uses a high-performance multi-louvered design that maximizes airflow. Every single radiator is leak tested before it leaves the factory at 150% of the operating pressure, so you know it’s going to hold up. And they’ve got industry-best packaging too; they even do a "10-foot drop test" to make sure it arrives in one piece. They really think of everything, from assembly to testing, ensuring that every component is installed and torqued properly.

Here are some specs if you’re into the nitty-gritty:

• Radiator Type: Crossflow
• Rows: 2
• Core Length: 27 15/16"
• Core Width: 21 9/16"
• Core Thickness: 1 5/8"
• Core Material: Aluminum
• Tank Material: Plastic
• Inlet Location: Upper Driver Side
• Outlet Location: Lower Passenger Side
• Inlet Diameter: 1 1/2"
• Outlet Diameter: 1 1/2"

For fitment, this radiator works with:

• Audi Q7 (2007-2015)
• Porsche Cayenne (2003-2010)
• Volkswagen Touareg (2004-2010)

Just a heads up—when you’re swapping out your radiator, make sure to check the old radiator pressure cap. It’s easy to overlook, but you don’t want to miss that little detail.

In short, if you want a reliable, high-performance radiator that won’t let you down, the CSF radiator is a solid choice. It’s built for the long haul, and it really shows in the engineering and materials used. You’ll be glad you made the upgrade.
