Injen 18-21 Subaru WRX STI H4-2.5L Turbo SP Aluminum Series Cold Air Intake - Wrinkle Black

If you're looking to get more out of your 2018-2021 Subaru WRX STI's turbocharger, this Injen SP Aluminum Series Short Ram Air Intake is a solid choice. It's designed to replace the restrictive factory airbox, allowing your engine to breathe more freely and unlock more of its potential power. This means you'll notice a difference in how the car pulls, especially when you're on the throttle.

The heart of this system is the 6061-T6 aluminum intake tube, which is mandrel-bent to ensure a smooth, uninterrupted path for air. This design, combined with Injen's patented MR Technology, helps maintain safe air-fuel ratios while boosting performance. You'll also get a more aggressive and throaty engine tone under acceleration, which many enthusiasts appreciate. The kit includes a serviceable SuperNano-Web dry air filter that offers good filtration and increased surface area for better airflow. Plus, it's a direct replacement, so installation is straightforward without needing a tune or worrying about check engine lights.

This intake is finished in a wrinkle black powder coat for a clean look under the hood. It's made in the USA and comes with Injen's limited lifetime warranty, giving you confidence in your purchase.
