COBB Redline Carbon Intake System STI MY15-21
REDLINE CARBON INTAKE
The COBB Redline carbon fiber intake blends performance and aesthetics. A full carbon fiber air duct feeds cold air from under the front of the hood to a large cone filter (35% greater surface area than the standard Cobb SF filter). The filtered air flow is funneled through a CFD-designed velocity stack minimizing turbulence and through an air flow straightener grid before passing through the mass air flow sensor. The velocity stack and MAF housing are made from high temperature plastic for low thermal transmission from the surrounding engine bay.
The airbox is crafted of carbon fiber 2x2 twill and features a high gloss finish that is heat and UV resistant in order to maintain its stunning appearance for many years to come.
The intake uses a billet aluminum plate to seal the fender side end of the airbox, but this plate can be removed if desired to increase airflow and audible intake noise. The airbox connects to the MAF housing via a billet aluminum plate as well. Both plates are anodized black and the black reinforced silicone hose is supplied with black anodized hose clamps to complete the sleek appearance.
Requires tuning either via Cobb's Off The Shelf maps or custom tuning. When running OTS use the same maps that support the Cobb SF intake.
Note: Hand laid carbon fiber parts may exhibit slight imperfections or weave variations.
