Unlock your engine’s true potential with the Injen SP Series Cold Air Intake, engineered specifically for the 2012 Honda Civic Si 2.4L. As Injen’s flagship intake system, the SP Series is designed to deliver maximum airflow, increased horsepower, and an aggressive intake tone—all while maintaining safe air/fuel ratios without the need for additional tuning.

Built around a precision-crafted 6061-T6 aluminum intake tube, this system provides a smooth, uninterrupted path for incoming air, reducing restriction and improving engine efficiency. Injen’s patented tuning technologies—including MegaRam (MR) Technology and Air Fusion Technology—optimize airflow dynamics to deliver real, usable power gains across the entire RPM range.

This intake system is dyno proven to produce gains of up to 15 horsepower and 12 lb-ft of torque, giving your Civic Si a noticeable boost in performance and throttle response.

At the heart of the system is the Injen SuperNano-Web dry air filter, offering superior filtration and increased surface area for enhanced airflow. Best of all, it’s fully serviceable and requires no oiling, making maintenance simple and hassle-free.

Designed for both performance and style, this intake delivers a deep, aggressive tone under acceleration and is available in multiple finishes to match your engine bay. Manufactured in Pomona, California, this system reflects Injen’s commitment to quality, innovation, and performance.
