Dealing with heat soak can be a real headache, especially if you’re pushing your 2015+ WRX to its limits. I’ve been there, and I know how frustrating it can be when your car just doesn’t perform as it should. That’s why I made the switch to an intercooler that was specifically designed for my WRX, and let me tell you, it’s been a game changer.

This isn’t just any intercooler; it’s crafted with a level of detail that you won’t find in cheaper alternatives. The folks behind this product really know their stuff. They’ve designed the cores to be custom-tailored for the WRX, which means you’re getting top-notch performance that’s built to last. The configuration of the internal and external fin packs is pretty ingenious—offset and staggered for optimal heat transfer and airflow. The external fins are densely packed to really suck away that heat, while the internal fins are designed for smooth flow. It’s all about finding that sweet spot, and they’ve nailed it.

Now, I get it—budget options are tempting. But trust me, those straight-through internal fin packs are like a one-way street for hot air. They can lead to higher intake temperatures, which messes with your timing and can even cause knock or misfires. Not worth the risk, right?

Let me introduce you to the ETS 2015+ WRX Intercooler. This thing is built for serious performance. The inlets and outlets are strategically placed in the middle of the core, which means air flows exactly how it should. Plus, they hand-port every inlet and outlet to reduce turbulence—no cheap welding here. It’s all about smooth, efficient airflow.

• The intercooler core is a massive 26 inches wide, which is no joke. With dimensions of 26" wide, 11.37" tall, and thickness options ranging from 3.0" to 5.0", this intercooler is designed for maximum heat transfer and minimal pressure drop.
• Thanks to precision TIG welding, it’s built tough. The lightweight end tank design not only makes it efficient but also helps improve handling by cutting down on weight.
• They’ve really gone the extra mile with the hand-porting of the inlet and outlet. This meticulous attention to detail minimizes turbulence and ensures that you’re getting the best flow possible, which translates to better performance on the road.
• And let’s not forget the ETS logo stenciled on the intercooler—adds a nice touch and shows you’re running with a brand that’s all about quality.

So, if you’ve got a Subaru WRX from 2015 to 2021, this intercooler is a solid upgrade that’ll help you unleash the full potential of your ride. Say goodbye to heat soak and hello to consistent performance!
