COBB Tuning Carbon Redline Intake System for VA Subaru WRX / WRX STi [725350]

The Redline carbon fiber intake, approved for all 50 states, flawlessly combines performance and visual appeal to create the ultimate intake system for the 2015-2021 WRX STI. Crafted from 2×2 twill carbon fiber and coated with a high-quality glossy clear finish, this intake system’s presence in the engine bay is eye-catching and leaves a lasting impression.

Construction

• The main airbox is constructed of multiple layers of 2×2 twill carbon fiber sheets for a proper carbon intake through and through. A 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 (compared to the standard SF Intake) pre-oiled filter and routed to the MAF housing, bolted to the airbox by a black anodized billet aluminum adapter. For a sleek install, the wire-reinforced black silicone coupler is sealed on either end with black anodized clamps. A second billet plate can be removed from the airbox’s fender side to increase the system’s airflow and audible intake sounds.

Velocity Stack MAF Housing

• This intake system utilizes several unique features to maintain optimal flow for performance while minimizing turbulence. A custom conical air-filter element, CFD-designed velocity stack, and remarkable 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.

Installation

• The installation process for the redline intake is straightforward, especially given its integrated airbox and scoop. Following the provided comprehensive instructions, users can easily install the included brackets, allowing the entire assembly to be fitted in just a few minutes. Once the initial installation is complete, maintaining and servicing the intake air filter is equally uncomplicated.

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.

Why COBB Tuning?

• They have raised the standard for Subaru performance intakes with the introduction of the redline carbon fiber intake. This intake system represents the top-tier choice for enthusiasts seeking an upgrade from the factory intake. It replaces the restrictive stock intake with a high-flowing and visually appealing system.
