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

The Injen Technology engineers spent abundant amounts of time designing, testing, and perfecting this performance Cold Air Intake system to develop some serious bolt-on power. The soul of this Cold Air Intake system is with our smooth, mandrel-bent, over-sized 3.00" O.D. T6-6061 aluminum tube that provides a smooth, uninterrupted path for highly efficient airflow and a look that will impress every time you open your hood! This intake system also features our patented MR (Mega Ram) Technology at the MAF for precise control over the fuel trims with no fear of check engine lights or additional electronic tuning.
