If you’re looking to give your Subaru STI a real boost, the AEM cold air intake system is where it’s at. This isn’t just another aftermarket part; it’s designed to genuinely enhance your ride’s horsepower and torque. The oversized AEM DRYFLOW synthetic washable air filter is a game-changer, letting your engine breathe easier while keeping the dirt out. You can go up to 100,000 miles between filter cleanings if you’re just cruising on the highway, which means less hassle and more time enjoying the drive.
The system features a mandrel-bent aluminum intake tube that not only looks slick but also helps maintain airflow efficiency. Plus, it comes with high-quality hardware to make installation a breeze—most folks can get it set up in under 90 minutes. Just a heads up, though: if you’re in California, you’ll want to check the CARB status for your specific vehicle because some intakes aren’t street legal there.
With AEM’s lifetime limited warranty backing it, you can trust that this system is built to last. The estimated horsepower gain is around 17 HP at 5224 RPM, which is pretty impressive for a simple upgrade. Seriously, if you want your STI to feel more alive, this cold air intake system is definitely worth considering.
