If you’re diving into a K-swap for your Civic or Integra, you’re going to want to keep that engine running cool, and that’s where the CSF High-Performance All-Aluminum Radiator comes in. With over 50 years in the game, CSF knows a thing or two about making radiators that can handle the heat—literally. This isn’t just any radiator; it’s designed for both the street and the track, making it perfect for those of us who push our rides to the limit. The heart of this radiator is its 2-row, 42mm core that features CSF's exclusive B-Tube Technology. Now, I know what you’re thinking—what’s so special about a tube? Well, instead of the usual oval shape, these B-tubes are engineered to maximize strength and cooling efficiency. They’re thinner and lighter than standard tubes, but don’t let that fool you; they’re tougher too. The design actually increases the heat transfer surface area by about 15%, which means you’re getting the cooling power of two smaller tubes without taking up extra space. And with dual liquid laminar flow, you can bet your engine’s going to stay at the right temperature, even when you’re pushing it hard. CSF didn’t stop there. The ultra-efficient multi-louvered fins are meticulously aligned to boost airflow through the radiator core. They’ve even tested these in a wind tunnel to ensure maximum heat rejection. It’s all about keeping that engine cool, right? One of the best parts? This radiator is a true drop-in fit. No modifications needed—just grab your OEM or aftermarket hoses and you’re good to go. The CNC machined brackets and fittings ensure durability, and the inlet and outlet connections are designed to match the original specs. Plus, it comes with a polished finish that looks as good as it performs. Here’s a quick rundown of what you’re getting:
- 2-Row 42mm Core with B-Tube Technology for superior cooling
- Ultra-efficient fins with a 6.5mm height for maximum surface area
- CNC machined "Quick-Connect" inlet/outlet connections
- All-aluminum construction for lightweight durability
- Drop-in fit—no hassle installation
