If you're looking to give your Subaru WRX or STI a little extra kick, the Injen Technology IS Performance short ram air intake is where it's at. I’ve had my hands on this system, and let me tell you, it’s not just another bolt-on part—it’s a game changer. The engineers at Injen really took their time crafting this thing, and it shows. You can expect some serious horsepower gains—up to 10 hp and 10 lb-ft of torque, and that’s no fluff. Best part? You won’t need any extra tuning to keep your air-fuel ratios in check, which is a huge plus for those of us who like to keep things simple.
The heart of this intake is its mandrel-bent aluminum tubing. This stuff is designed to create a smooth pathway for airflow, which means you’re getting a more efficient intake experience. And let’s not forget about the Injen SuperNano-Web dry air filter. It’s fully serviceable, and with its increased surface area, it allows for better airflow while keeping dirt and debris out. That’s a win-win if you ask me.
Now, if you’re like me and enjoy a bit of sound with your power, you’ll appreciate the aggressive tone this intake produces when you really step on it. It’s got that throaty growl that makes driving a lot more enjoyable, especially when you’re pushing the limits.
Worried about looks? You’ve got options. This kit comes in a polished finish or a sleek powder-coated laser black, so you can pick what suits your ride best. And just to put your mind at ease, Injen backs this product with their limited lifetime warranty, which is a nice touch.
Here’s a quick rundown of what you’re getting:
So, if you've got a 2002-2007 Subaru STI or WRX, this Injen IS short ram air intake system is definitely worth considering. It’s all about that extra power and sound that makes driving a blast.
