    Our performance air intake for the 2017-2021 Honda Civic Si is finally here! This intake was engineered specifically for the new turbocharged Civic and is a direct-fit modification that will provide enhanced engine performance and improved throttle response. Plus, it will add a little flair under the hood! This intake has a noticeably unique and aggressive tone under acceleration and boost. The steel wire-reinforced silicone intake arm improves airflow and keeps intake air temperatures under control as opposed to an aluminum design.

    The black powder-coated steel airbox covers and protects the Mishimoto high performance air filter from engine bay heat, while also eliminating the possibility of hydrolock with the placement being closer to the hood. The box makes use of the stock air diverter found right underneath the hood, which is used to direct airflow into the stock airbox. The MAF housing has a venturi-style inlet, improving the airflow compared to the conventional MAF housing design. This intake makes consistent dyno-proven gains of about 4 hp and 4 ft-lbs of torque and was designed in the USA at our Delaware headquarters. This unit is a complete bolt-on part that functions perfectly with the stock tune and includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
