Description
Enhance your Honda Civic Si with the Mishimoto Performance Air Intake designed specifically for models from 2006 to 2011. This high-performance intake replaces the restrictive stock airbox, delivering noticeable power gains and a richer engine sound. Engineered with precision, it offers dyno-proven increases of up to 8 horsepower and 6 torque, providing an immediate boost to your vehicle’s street or autocross performance while maintaining optimal air/fuel ratios for reliability.
The kit features a mandrel-bent aluminum intake pipe with a sleek wrinkle black powder-coated finish, ensuring durability and a clean look under the hood. Its CNC-machined mass airflow sensor housing guarantees accurate readings, resulting in a smooth and responsive power band. To combat heat soak and reduce intake temperatures, a powder-coated heat shield is included, positioned between the air filter and the hot exhaust manifold. The Mishimoto free-flowing air filter boasts an 85-percent larger surface area for improved airflow and filtering efficiency, ensuring dirt and debris are effectively captured while supporting a lifetime of service with its reusable oil filter.
Installation is straightforward, with all necessary hardware, a silicone coupler, and clamps included, enabling a quick bolt-on upgrade that can be completed in under an hour and works flawlessly with the stock tune. The intake also produces an aggressive and rich intake tone, especially noticeable when VTEC activates, adding an auditory enhancement to the driving experience. Designed in Delaware, USA, the Mishimoto Civic Si Performance Air Intake comes with a lifetime warranty, ensuring quality and customer satisfaction. This product complies with EPA standards and is not CARB-registered, making it suitable for street use where permitted.
