Using this Injen cold air intake is easy. First, make sure your engine is cool. Then, carefully remove the old air intake following the standard procedures for your 2017+ Honda Civic Si or Type R. Install the new Injen SP cold air intake in place, making sure all connections are secure. Start your engine and listen to the great sound it makes! When it comes to maintenance, check the Injen SuperNano - Web dry air filter regularly. If it's dirty, clean it according to the instructions. Don't forget to keep an eye on the Air - fuel (A/F) ratio. If you notice any strange noises or performance issues, stop using the vehicle and check the intake system for any loose parts or damage. With proper use and maintenance, this intake will serve you well for a long time, thanks to the limited Lifetime Warranty.
