Injen 2017+ Honda Civic Si 1.5L Polished Cold Air Intake

If you're looking to get more out of your 2017-2020 Honda Civic Si, especially when it comes to breathing easier and making more power, this Injen SP Series Cold Air Intake is a solid choice. This system is designed to replace your restrictive factory airbox, allowing your turbocharged 1.5L engine to take in more air, which can lead to noticeable improvements in horsepower and torque.

The intake tube itself is made from 6061-T6 aluminum, polished to a nice finish, and features Injen's patented MegaRam and Air Fusion technologies. These aren't just fancy names; they represent Injen's approach to tuning the intake tract to optimize airflow and ensure your engine maintains a safe air-fuel ratio even with the increased air volume. This means you get the performance benefits without compromising engine health. It also comes with a serviceable SuperNano-Web dry air filter, which offers good filtration and a large surface area for maximum airflow. You'll also notice a more aggressive, throaty sound when you step on the gas.

This kit is designed as a direct fit for your Civic Si, meaning it installs without needing additional tuning for most applications. It's a popular upgrade for a reason, offering a good balance of performance, sound, and aesthetics.
