Subaru WRX STI Performance Air Intake - COBB - Air Box - 2015–2018. A purpose-built intake and airbox that improves airflow and helps your EJ-powered STI breathe efficiently.

COBB pairs a serviceable high-flow filter with a precision MAF housing and a fitted airbox that draws cooler, cleaner air than stock. The enclosure helps curb heat soak and turbulence for steadier temps and stable metering. It installs with common tools using the supplied hardware and provides a reliable base for custom tuning. For best results, a calibration is recommended after installation.

Features

• Direct fit for 2015–2018 Subaru WRX STI (EJ)
