Enhance your 2006-2011 Honda Civic Si with the Mishimoto Performance Air Intake, designed specifically for optimal fit and performance. This upgrade replaces the factory airbox to deliver increased horsepower, torque, and a more aggressive intake sound. Featuring a mandrel-bent aluminum pipe with a choice of polished or wrinkle black powder-coated finish, the intake ensures smooth airflow and durability. The CNC-machined MAF housing guarantees precise and consistent readings, contributing to a seamless power delivery across the RPM range.
The kit includes a high-flow Mishimoto air filter with 85% greater surface area for improved airflow and dirt filtration, along with a serviceable design that supports long-term use. To combat heat soak, a powder-coated heat shield is included, which effectively reduces intake air temperatures by blocking hot engine bay air. This ensures the engine receives cooler, denser air for better combustion efficiency.
Installation is straightforward, taking less than an hour with all necessary hardware, silicone coupler, and clamps provided. The intake kit works perfectly with the stock tune, requiring no ECU modifications, and is compatible with the vehicle's existing VTEC system for an enhanced driving experience. The aggressive intake tone under acceleration adds to the sporty feel, especially noticeable when VTEC engages. Designed in Delaware, USA, and backed by Mishimoto’s lifetime warranty, this performance upgrade is ideal for street and autocross enthusiasts seeking reliable power gains and a deepened engine sound.
This product is compliant with EPA standards and carries the CARB EO number D-759-1, making it suitable for use in regions with emissions regulations. Whether you're upgrading for daily driving or spirited autocross sessions, the Mishimoto Honda Civic Si Performance Air Intake offers a significant upgrade in performance and sound quality.
