Extreme Turbo Systems Anodized Purple 4.0" Front Mount Intercooler Upgrade Subaru STI 2015-2021
$1159.00

If you're diving into the world of performance upgrades, you know that the intercooler is pretty much the heart of any solid kit. That’s where our intercoolers come in. We’ve got a core design that’s not just impressive on paper—it’s been proven on the track. Seriously, Kozmic Motorsports hit an 8.05 @ 184 mph using one of our off-the-shelf units. That’s some serious cred right there.

What makes our intercoolers stand out? For starters, they feature a killer internal fin pack that maximizes efficiency. It’s not just about looking good; this design helps keep your air temps down, which means better performance. Plus, we pressure test these bad boys up to 35 PSI, so you know they can handle the heat.

We also take pride in our craftsmanship. Each intercooler is hand-fabricated with TIG-welded end tanks, ensuring durability and a snug fit. The core itself is a massive 26” x 11.5”, giving you plenty of surface area to work with. And did I mention these are built right here in the USA? You’re not just buying a product; you’re supporting local craftsmanship.

Here’s the rundown on what you get:

  • Pressure tested to a solid 35 PSI
  • Hand fabricated and TIG welded end tanks for that perfect fit
  • Record-setting core design that’s proven to perform
  • A hefty 26"x11.5" core size to keep those intake temps in check
  • Made in the USA
  • Lifetime warranty—because we stand by our stuff

Now, let’s talk fitment. This intercooler is specifically designed for the Subaru STI 2015-2021. So if you’re looking to upgrade your ride, this is the piece you need. It’s the 200-30-IC-030 Extreme Turbo Systems Anodized Purple 4.0" Front Mount Intercooler Upgrade. Trust me, your engine will thank you.
