Product Description

Is there ever a bad time for Carbon Fiber? We didn't think so. The COBB Redline Carbon Fiber Intake is the crown jewel of the COBB catalog. Standard plastic intakes do the job, but they don't inspire envy. This system replaces the boring factory plastic tubing and airbox lid with gorgeous, hand-laid carbon fiber components. The weave is a classic 2x2 twill (matching most high-end aero parts), finished in a deep gloss clear coat that resists engine bay heat and looks incredible under garage lights.

You buy an intake for the noise. The stock Focus ST/RS intake is designed to be quiet, hiding the best sounds the 2.0L and 2.3L engines make. COBB fixes this by using a high-flow Dual Cone Green Filter. By opening up the induction system, you finally get to hear the turbo spooling up and the bypass valve venting between shifts. It adds a visceral layer to the driving experience that makes every gear change satisfying.

This isn't just dress-up parts; it's functional engineering. The piping diameter is increased to a full 3 inches, reducing restriction and allowing the turbo to draw in air with less resistance. The kit includes a bespoke Redline Badge and blacked-out hardware to keep the aesthetics clean and cohesive. Because these parts are hand-laid, slight variations in the weave pattern can occur—a hallmark of genuine carbon fiber construction, not mass-produced plastic.

The COBB Redline Series represents the highest tier of aftermarket parts. It’s for the enthusiast who wants zero compromises between performance and aesthetics. Whether building a show car or a track weapon, this intake delivers the airflow your engine needs and the style your build deserves. It’s refined, it’s loud when you want it to be, and it fits perfectly. Treat your Focus to the best.
