If you're looking to boost your Subaru STI's performance, you really can't go wrong with this top mount intercooler from Extreme Turbo Systems. I’ve had mine on for a while now, and let me tell you, it’s a game changer. This isn’t just any intercooler; it’s a direct bolt-on upgrade specifically designed for the 2008 and newer STI models. The first thing that stands out is the size of the core—it's a hefty 19x7x4 inches with a whopping 31 charge rows. Most other options out there only have around 24-25 charge rows, which means you’re getting more heat transfer with this setup. We’re talking 62 heat transfer plates compared to the usual 48 on the competitors. That’s a significant difference when it comes to keeping your intake temperatures down during those spirited drives or track days.
What I really appreciate is that this intercooler is made for our cars, not a generic part that requires a bunch of modifications. You won’t have to worry about rerouting your A/C lines, which is a real hassle with some other intercoolers. Plus, the way it mounts the blow-off valve using studs instead of bolts is a smart move. I’ve stripped out my fair share of bolt holes in the past, so having that extra security is a relief. And at just 20 lbs, it’s not going to weigh your ride down.
Here’s a quick rundown of what you’re getting:
- Large 19x7x4 intercooler core for serious cooling
- Direct bolt-on installation—no fuss, no mess
- Studs for the blow-off valve to prevent stripping
- Designed to clear the A/C line, keeping everything neat
- 31 charge rows for maximum heat transfer efficiency
- Weight: 20 lbs
This intercooler fits perfectly on Subaru STI models from 2008 to 2014, and it’s definitely worth considering if you're serious about performance upgrades. Trust me, once you get this installed, you’ll notice the difference in throttle response and overall power. It’s one of those mods that you can feel right away.
