Using this Injen cold air intake is easy. First, make sure your engine is cool. Then, carefully remove the old air intake following your car's manual. Install the Injen SP intake in its place, connecting all the parts securely. For best results, ensure all connections are tight. When it comes to maintenance, regularly check the Injen SuperNano - Web dry air filter. If it's dirty, you can clean it according to the filter's instructions. This will keep the airflow and filtration working well. Also, make sure to check the intake tube for any signs of damage or loose connections during your regular car checks. Keep in mind that this intake is designed specifically for 2017 - 2020 Honda Civic Si and 2017 - 2018 Honda Civic Type R, so don't try to use it on other models without consulting Injen.
