Mishimoto Performance Air Intake Kit for 2017-2020 Honda Civic Si - Red (MMAI-CIV-17SIRD)

Fits 2017-2020 Honda Civic Si.

Enhance the breathing and response of your turbocharged L15B7 engine with the Mishimoto Performance Air Intake Kit. Engineered specifically for the 10th-generation Civic Si, this direct-fit upgrade replaces the restrictive factory airbox with a system designed for 37% less restriction. This kit delivers dyno-proven gains of 4 whp and 4 wtq on the stock tune while providing a significantly more aggressive induction and turbocharger sound.

This system features a steel wire reinforced silicone intake arm, which maintains structural integrity under vacuum and offers superior thermal resistance compared to aluminum tubes, keeping intake air temperatures (IATs) lower. The black powder-coated steel airbox isolates the high-performance reusable filter from engine bay heat, utilizing the factory hood-mounted air diverter to draw in fresh ambient air. The custom-engineered MAF housing incorporates a venturi-style inlet to ensure smooth, laminar airflow across the sensor for reliable performance without triggering check engine lights.
