Injen 15-21 Subaru WRX 2.0L 4 Cyl. Wrinkle Red Cold Air Intake

The 3.00-inch diameter, mandrel-bent T6-6061 aluminum tubing in this Injen cold air intake system is designed to provide a smooth, uninterrupted path for air entering your 2015-2021 Subaru WRX's 2.0L turbo engine. This design choice is key to improving airflow efficiency, which is crucial for maximizing the performance of turbocharged vehicles. The intake also incorporates Injen's patented MR Technology at the MAF sensor location, helping to ensure precise fuel trim control without triggering check engine lights or requiring additional electronic tuning.

This Injen intake system includes a custom-designed heatshield and cover specifically for the WRX application. This helps to isolate the intake from under-hood heat, maintaining cooler air temperatures for better density and performance. The result, as tested on a chassis dyno, is an impressive gain of up to 24 horsepower and 20 lb-ft of torque, offering a noticeable improvement in both acceleration and sound. The Wrinkle Red finish adds a distinct look to your engine bay, complementing the overall aggressive growl this intake produces under acceleration.

Installation is straightforward, with stainless steel band clamps featuring an inner protective liner for a secure and clean finish. The system uses a fully serviceable Injen SuperNano-Web dry air filter, which is designed for maximum airflow and easy maintenance. This intake is designed to work with the stock calibration, making it a direct bolt-on upgrade for your WRX. Injen backs this intake with a limited lifetime warranty, reflecting their confidence in its well-built construction and performance.
