Cold Air Intake for Ford Focus ST (2013-2018) 2.0L Turbo Engine - Black

Unlock hidden performance from your Focus ST or RS with this precision-engineered cold air intake system—delivering cooler, denser air for improved throttle response, enhanced turbo spool, and a satisfying aggressive induction sound that makes every drive more engaging.

Turn Your Focus ST/RS Into the Turbocharged Beast It Was Meant to Be

The Ford Focus ST and RS represent a legendary chapter in Ford's performance lineup—direct descendants of rally-bred engineering that brought European hot hatch culture to American enthusiasts. With the ST's 252 hp EcoBoost 2.0L and the RS's race-inspired 350 hp 2.3L engine, these platforms are built for spirited driving. But there's a catch: Ford's factory airbox prioritizes quiet operation over maximum airflow, creating a bottleneck that limits your turbo's potential.

This Performance Cold Air Intake System eliminates that restriction. By replacing the restrictive factory components with a high-flow induction path and integrated heat shield, it feeds your turbocharged engine the volume of cool, oxygen-rich air it craves. The result? Improved throttle response, enhanced turbo spool, and an estimated gain of 8-12 horsepower and 10-15 lb-ft of torque across the powerband. Whether you're carving canyon roads or hitting your local autocross, this upgrade ensures your Focus performs at its peak.

Key Features at a Glance

• Proven Power Gains: Delivers an estimated 8-12 hp and 10-15 lb-ft torque increase through optimized airflow and reduced intake temperatures.
• Thermal Heat Shield: Blocks rising engine bay heat to maintain consistent intake air temperatures for reliable performance.
• High-Flow Filter: Captures harmful debris while maximizing airflow—cleanable and reusable for long-term value.
• Aggressive Sound: Enhances induction noise for a deeper, more engaging turbo growl during acceleration.
• Direct Bolt-On Fitment: Designed specifically for 2013-2018 Focus ST (2.0L) and 2016-2018 RS (2.3L) models with no cutting or drilling required.

How It's Used: Installation & Fitment

This is a straightforward bolt-on upgrade that most DIYers can complete in 60-90 minutes with basic hand tools. The kit includes precision-engineered induction piping, a thermal heat shield, high-flow air filter, and all necessary couplers, clamps, and hardware. Installation requires removing the factory airbox and routing the new intake components into place. Always disconnect the negative battery terminal for at least one minute after installation to allow your ECU to relearn the new airflow parameters and optimize performance.

Product Durability & Material Details

Constructed from durable aluminum piping and high-grade silicone couplers, this system withstands the heat cycling and vibration common in turbocharged applications. The integrated heat shield uses reflective material to deflect radiant heat from the exhaust manifold and turbo, ensuring consistent intake temperatures even during hard driving. The high-flow filter features multi-layer cotton gauze construction that captures contaminants while allowing maximum airflow—cleanable and reusable for the life of your vehicle.

Your Benefits at a Glance

• Instant Throttle Response: Eliminates intake lag for more immediate acceleration and sharper turbo spool.
• Improved Fuel Efficiency: Optimized air-to-fuel ratios can lead to more efficient combustion during normal driving conditions.
• Track-Ready Performance: Maintains consistent airflow and power delivery during extended spirited driving or track sessions.
