If you’re looking to amp up the performance of your 2015-2021 Subaru WRX with that H4-2.0L Turbo engine, the Injen SP1209 Short Ram Air Intake is a solid choice. I’ve had my hands on this intake, and let me tell you—it’s a game changer.

Installation? Super straightforward. You can get it set up without needing a degree in engineering. Once it’s in, your turbo engine can finally breathe properly, transforming that built-up pressure into the kind of power you’ve been itching for. We’re talking about a dyno-proven boost of up to 24 horsepower and 20 lb-ft of torque. You can actually feel the difference when you hit the gas, and the sound? It’s an aggressive growl that’ll make you smile every time you accelerate.

The heart of this system is the oversized 3.00" O.D. T6-6061 aluminum tube. It’s mandrel-bent, which means airflow is smooth and efficient—no turbulence here. Plus, it looks great when you pop the hood. Injen’s patented MR (Mega Ram) Technology also ensures that your fuel trims stay in check, so you won’t be dealing with pesky check engine lights or the need for additional tuning.

Another cool feature is the custom-designed heatshield that comes with it. This isn’t just for looks; it helps protect against under-hood heat, keeping your intake nice and cool. It’s a clean setup that fits like it was made for your WRX right from the factory.

And if you’re into aesthetics, Injen offers this intake in a few finishes: polished, wrinkle black, and wrinkle red. So you can choose what suits your ride best. Oh, and don’t forget about the Injen Technology limited lifetime warranty that backs this product. That’s peace of mind right there.

Here’s a quick rundown of what you’re getting:

  • Up to 24 hp and 20 lb-ft of torque gains
  • Compatible with stock calibration
  • Max airflow design
  • 3.00in mandrel-bent 6061-T6 aluminum tubing
  • Application-specific heatshield
  • Fully serviceable Injen SuperNano-Web dry air filter
  • Made in Pomona, California

Just a heads up, this product isn’t CARB exempt, so if you’re in California, you’ll need to look elsewhere. But if you’re ready to take your WRX to the next level, the Injen SP1209 is definitely worth considering.
