SUBARU REDLINE CARBON FIBER INTAKE WRX 2015-2021

The COBB Redline Carbon Fiber Intake System for the 2015–2021 Subaru WRX is the ultimate combination of elite performance, premium materials, and refined engine bay styling. Built entirely from hand-laid 2x2 twill carbon fiber and finished with a high-gloss clear coat, this intake system not only delivers power—it turns heads every time you pop the hood.

The intake’s main airbox is a true carbon fiber construction, designed to resist heat and UV degradation while providing structural integrity and lasting aesthetics. At the front, a bespoke COBB Redline black badge is integrated into the ducting for a clean, aggressive look. Air is channeled through a high-flow pre-oiled cone filter and into a custom-designed MAF housing, engineered to optimize flow and reduce turbulence.

This system uses a CFD-modeled velocity stack and integrated airflow straightener grid, ensuring clean, consistent airflow across the Mass Air Flow sensor. This maintains accurate readings, improves throttle response, and supports smooth tuning performance. The MAF housing itself is made from a lightweight, high-temp composite that reduces heat transfer compared to metal designs.

The install process is straightforward and fully reversible. All necessary hardware is included, and the custom billet aluminum lid secures the air filter inside the box using a rugged billet dial. This tool-free system makes servicing the filter fast and easy—simply twist the dial to access or replace the filter within seconds.

This intake is fully compatible with COBB Off The Shelf Maps. Look for calibrations marked “+Redline” on your Accessport or the COBB website to ensure proper tuning support.

Note: This intake is not compatible with the COBB Radiator Shroud.
