Using the Injen SP cold air intake system is easy. First, make sure your car's engine is cool before installation. Follow the included instructions carefully to install the intake system properly. Once installed, start your car and enjoy the improved performance and sound. When it comes to maintenance, check the air filter regularly. If it looks dirty, clean it according to the filter's cleaning instructions. Keep in mind that this intake system is designed for specific Hyundai models (2019 - 2020 Elantra GT N Line, 2019 - 2020 Veloster Turbo, Turbo R - Spec, and Turbo Ultimate). Don't try to install it on other models without proper modification. Also, avoid exposing the intake system to extreme moisture or debris for long periods, as this could affect its performance. With proper use and maintenance, your Injen intake system will serve you well for a long time.
