Cold Air Intake for Ford Fiesta (2011-2013) 1.6L Engine - Red

Optimize Flow and Throttle Response for Your Ford Fiesta Sigma Engine

Who It’s For: Designed specifically for 2011-2013 Ford Fiesta owners running the 1.6L Sigma engine family. This is for the driver who wants to move beyond the conservative factory tuning and wake up the responsiveness of their daily commuter or weekend canyon car.

The Problem: The stock 1.6L Sigma setup is heavily restricted by a massive, baffled plastic air box and a thick paper filter designed more for noise suppression than actual performance. This creates a bottleneck that causes sluggish throttle response and heat soak, especially during spirited driving or in high-traffic situations.

The Solution: We engineered this intake to eliminate the factory restrictions of the Sigma engine. By utilizing high-flow T304 aluminum and a low-restriction washable filter, we straighten the air path and increase the volume of oxygen available for combustion, delivering a noticeable improvement in mid-range torque and a much-needed sporty growl under load.

Why This is the Ultimate Upgrade

• Enhanced Power Delivery: Provides up to a 10% increase in horsepower and torque by reducing pumping losses and allowing the engine to breathe more freely.
• Premium Construction: Built with T304 lightweight aluminum piping that resists corrosion and dissipates heat faster than the bulky factory plastic components.
• Simple Bolt-On Installation: This kit is a direct replacement for the factory air box and intake tube; it can be installed in under 60 minutes using basic hand tools without any permanent modifications to your vehicle.
