Extreme Turbo Systems Anodized Purple 3.0" Front Mount Intercooler Upgrade Subaru STI 2015-2021
$959.00

If you're diving into the world of intercoolers, you know that the heart of any solid kit is the intercooler itself. That's where this beast comes in. We're talking about a top-notch unit from Extreme Turbo Systems that uses a killer core design—one that’s been setting records and pushing the limits. This isn't just some off-the-shelf part; it’s built to perform. The internal fin pack is designed for maximum efficiency, making sure that your engine is getting the cold air it craves, especially when you're pushing it hard.

Take it from Kozmic Motorsports, who managed to clock an impressive 8.05 @ 184 mph using one of these bad boys. That’s proof enough that you’re getting a product that can handle serious power without breaking a sweat.

Now, let’s break down what makes this intercooler stand out:

  • It’s pressure tested to a whopping 35 PSI, so you know it can take the heat (literally).
  • Each unit is hand-fabricated with TIG-welded end tanks, ensuring durability and a tight fit.
  • The core design is nothing short of record-setting—it's designed to maximize airflow and minimize heat soak.
  • With a massive 26"x11.5" core size, this intercooler is built for serious performance.
  • And yes, it’s proudly made in the USA, so you can feel good about supporting local craftsmanship.
  • Plus, it comes with a lifetime warranty, which is a nice peace of mind for those of us who push our cars to the limit.

As for fitment, this intercooler is specifically designed for the Subaru STI models from 2015 to 2021. If you own one of these, then this 3.0" front mount intercooler upgrade in anodized purple is a no-brainer. It’s not just about looks; it’s about performance, reliability, and making sure your ride stays cool under pressure.
