Upgrade your 2017-2020 Honda Civic Si with the Injen Technology SP1584WR Short Ram Cold Air Intake System, designed to maximize performance and enhance your driving experience. Crafted with a 2.75-inch aluminum intake tube, this intake system facilitates deep breathing for the turbocharged 1.5L engine, resulting in noticeable power gains. Our engineers meticulously designed smooth transitions within the intake piping to reduce airflow restrictions, allowing your engine to produce more horsepower and torque, with dyno-proven gains of up to 16 HP and 14 ft. lbs. of torque. The system includes a fully serviceable SuperNano-Web dry air filter, which not only ensures optimal airflow but also maintains excellent filtration capacity for long-term durability. Featuring Injen's proprietary MegaRam (MR) Technology and Air Fusion Technology, this intake optimizes air delivery and tuning during manufacturing, eliminating the need for additional electronic tuning while maintaining ideal air-fuel ratios. The custom heatshield enhances performance by keeping inlet air temperatures low, especially during aggressive driving, while the Wrinkle Red finish adds a bold, sporty appearance to your engine bay. Installation is straightforward, and the durable 6061-T6 aluminum construction guarantees long-lasting performance. Designed and manufactured in Pomona, California, this intake system exemplifies quality and performance. Please note, this product requires acknowledgment of non-CARB exemption and is not legal for use in California or on California-registered vehicles. Enhance your vehicle's sound with an aggressive engine tone under full throttle, and enjoy the peace of mind provided by Injen’s limited lifetime warranty. Whether you're looking for increased horsepower, improved airflow, or a striking aesthetic upgrade, the Injen SP1584WR intake system is engineered to deliver exceptional results for your Honda Civic Si.
