K&N 2017 Honda Civic Si 1.5L Typhoon Performance Air Intake System

This K&N Typhoon Performance Air Intake System is built specifically for your 2017-2020 Honda Civic Si with the 1.5L turbocharged engine. What you get in the box is a mandrel-bent aluminum intake tube, a washable and reusable K&N High-Flow Air Filter with oiled cotton media, and a custom heat shield designed to keep engine bay heat away from the intake air. This setup is designed to help your engine breathe easier, leading to a guaranteed increase in horsepower and torque.

The aluminum intake tube is bent using a mandrel process, which means it maintains a consistent diameter throughout. This smooth airflow path helps your engine pull in more air efficiently. The oversized, conical air filter is built to last, allowing you to go up to 100,000 miles between cleanings under normal highway driving conditions. K&N backs this system with their Million Mile Limited Warranty, and it's designed to install in under 90 minutes without voiding your vehicle's warranty.

Keep in mind that this intake system is not legal for sale or use in California due to emissions regulations. If you're looking to improve your Civic Si's performance and sound, this K&N intake is a solid option.
