Cobb 15-21 Subaru STI Redline Carbon Fiber Intake Kit

Description

Cobb 15-21 Subaru STI Redline Carbon Fiber Intake System – Gloss Finish

The main airbox is constructed of multiple layers of 2×2 twill carbon fiber sheets for a true carbon intake through and through. High quality gloss clear finish provides fade resistance from heat and UV light. A bespoke black Redline badge sits at the front of the integrated intake ducting. Air is filtered through a 35% larger (when compared to the standard SF Intake) pre-oiled filter and routed to the MAF housing which is bolted to the airbox by way of a black anodized billet aluminum adapter. The wire-reinforced black silicone coupler is sealed on either end with black anodized clamps for a very sleek install. A second billet plate can be removed from the fender side of the airbox to increase airflow and audible intake sounds of the system.

Velocity Stack MAF Housing:
This intake system utilizes several unique features in an effort to maintain optimal flow for performance while minimizing turbulence. A custom conical air-filter element, CFD-designed velocity stack and unique air flow straightener grid are designed to smooth the incoming air flow as it passes the Mass Air Flow sensor for precise readings. The one piece high temperature plastic composite design saves weight and reduces heat transfer. While this may not sound or look like much the MAF housing design in all the Cobb Intakes is hands down the best on market and give a super clean easy to tune with MAF sensor signal under all load ranges.

Installation:
Installation of the Redline Intake is as simple as it comes for intakes with an integrated airbox and scoop. Follow our detailed instructions to install the supplied brackets and the entire assembly can be dropped in within a few minutes. Serviceability of the intake air filter is also straight forward once the initial installation has been completed.

Calibration:
The Redline Carbon Fiber intake is compatible with existing COBB Off The Shelf Maps that support the standard SF Intake. For 2015-2021 STIs, that includes Stage 1+SF and Stage 3 OTS Maps. To get the most out of your STI with the Cobb redline intake we do highly recommend getting a custom STI Etune from our partners at Brewed Motorsports.
