Cold Air Intake for Honda Civic Si (2016-2021) with 1.5L l4 DOHC Turbo Engine Blue

Maximize your Civic Si's turbocharged potential with a complete sealed cold air intake system engineered for real gains—not just noise.

More Power, Better Response, Unmistakable Sound

The 10th-gen Honda Civic Si brought back the turbocharged thrill that enthusiasts had been craving. With its 1.5L turbo four-cylinder, this platform responds incredibly well to breathing modifications. The EVO1501 Evolution cold air intake replaces your restrictive factory airbox with a fully sealed system that pulls cooler, denser air directly to your engine—resulting in measurable horsepower and torque gains, sharper throttle response, and that satisfying turbo spool you'll hear on every pull.

This isn't a generic universal kit. It's precision-engineered specifically for the 2017-2018 Civic Si, designed with advanced CAD modeling to ensure perfect fitment and maximum airflow. The one-piece sealed housing protects your engine from heat soak, while the patent-pending Twist-Lock system keeps the Super Nano-Web dry filter securely in place—no clamps, no worries.

Key Features at a Glance

• Sealed Cold Air Design: Draws cooler air from outside the engine bay for consistent power and improved combustion efficiency
• Super Nano-Web Dry Filter: High-flow filtration that captures contaminants without sacrificing airflow—washable and reusable
