If you’re really into keeping your engine cool, you’ve got to check out the CSF radiator. Seriously, this isn’t just any radiator; it’s built for those who take their car’s performance seriously. CSF has been around for over 50 years, cranking out radiators for just about every car you can think of—from Acura to Volkswagen. They’ve sold over 30 million units worldwide, so you know they’ve got the experience to back it up.

What’s great about CSF is their attention to detail. They offer a variety of radiator types—Copper-Brass, Plastic-Copper-Brass, Plastic-Aluminum, and All Aluminum—so you can find exactly what you need. These radiators are made to match the materials and style of the original equipment, which means you’re not sacrificing quality for an aftermarket part.

Now, let’s get into the nitty-gritty. The CSF radiators are designed with high-performance standards in mind. They’ve even gone through wind tunnel testing to validate cooling performance, so you know they’re not just talking the talk. The construction features an OEM-specified Plastic Tank-Aluminum Core, which is not just any plastic; it’s made from virgin grade engineered resins that are glass-filled for extra durability. That means it can handle the heat—literally. The gaskets are made from special grade EPDM rubber, which can withstand extreme temperatures down to -120°F.

Here are some key features you’ll appreciate:

• OEM specified Plastic Tank-Aluminum Core Construction
• Tanks made from Virgin Grade Engineered plastic resins for added strength
• High Performance Multi-Louvered Design fins for efficient cooling
• 100% leak tested at 150% of operating pressure before leaving the factory
• Industry-best packaging that can survive a 10-foot drop test
• All components are installed and tested during assembly

When it comes to specs, this radiator is a downflow type with a single row. The core measures 14 3/4" in length, 27 1/16" in width, and 1 1/4" in thickness. Both the inlet and outlet have a diameter of 1 3/8", with the inlet located at the upper center and the outlet on the lower driver side. It's built to fit perfectly in your Mitsubishi Lancer Evolution from 2003 to 2006, as well as the 2007 Lancer.

Just a heads-up: if you’re swapping out your radiator, make sure to check the old pressure cap for wear. It’s a small detail that can save you a headache down the line.

In short, if you want a radiator that’s tough, reliable, and built for performance, the CSF radiator is a solid choice. You’ll be keeping your engine cool and happy, and that’s what it’s all about.
