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

The 3.00-inch diameter, mandrel-bent 6061-T6 aluminum tubing in this Injen cold air intake is key to its performance. This smooth, oversized tube creates an uninterrupted path for air, helping your 2015-2021 Subaru WRX's turbocharger breathe more freely. It's designed to impress visually, too, with a durable wrinkle black finish that looks sharp under the hood.

Injen's patented MR (Mega Ram) Technology is integrated into the MAF housing, which helps maintain precise control over your engine's fuel trims. This means you can often install this intake without needing an ECU tune or worrying about check engine lights. The system also includes a custom-designed heat shield and cover, specifically made for the WRX, to block under-hood heat and give your engine bay a clean, finished look. On the chassis dyno, this intake has shown gains of up to 24 horsepower and 20 lb-ft of torque, which translates to a more responsive feel when you accelerate.

This Injen SP1209WB intake comes with a fully serviceable SuperNano-Web dry air filter that's easy to clean and reuse. All the necessary hardware, including stainless steel band clamps with protective liners, is included for installation. Injen also backs this intake with a limited lifetime warranty, reflecting their confidence in its build quality and performance.
