Enhance the performance of your 2017-2020 Honda Civic Si with the Injen Technology SP1584P Short Ram Cold Air Intake. Designed specifically for the 1.5L turbocharged engine, this intake system is engineered to unlock hidden power and improve airflow efficiency. Our team of engineers meticulously crafted this intake with a large 2.75-inch aluminum tube featuring smooth transitions, reducing restriction and allowing your engine to breathe more freely. This design results in measurable gains of up to 16 horsepower and 14 lb-ft of torque, providing a noticeable boost in acceleration and responsiveness. The polished finish not only offers an eye-catching look but also resists corrosion, ensuring durability and style over time.
The intake system includes a fully serviceable SuperNano-Web dry air filter, which maintains optimal airflow and filtration. Thanks to Injen’s patented MegaRam (MR) technology and Air Fusion process, this intake is finely tuned during manufacturing for maximum performance without requiring any additional electronic tuning. The custom-designed heatshield helps keep inlet air temperatures low, further enhancing power output and engine efficiency. Installation is straightforward, with hardware and instructions included, making this a versatile upgrade for your vehicle. Please note that this product is not CARB exempt and is intended for off-road use only, and it is compatible with a range of finishes including polished, black, and wrinkle red to match your aesthetic preferences.
Built in Pomona, California, this high-quality intake system adheres to rigorous manufacturing standards and comes with a limited lifetime warranty. The Injen short ram intake not only boosts engine performance but also enhances the aggressive engine tone under full throttle, delivering a more engaging driving experience. For those seeking further upgrades, Injen offers compatible components such as intercoolers, exhausts, and charge pipes, making it easy to build a comprehensive performance package.
