Using this Injen cold air intake is easy. First, make sure your engine is cool. Then, carefully replace your old air intake with this new SP series intake. It's designed to fit specific models, so ensure you have the right fit for your vehicle. When it comes to maintenance, check the Injen SuperNano - Web dry air filter regularly. If it looks dirty, you can service it according to the instructions. Also, keep an eye on the air - fuel ratio; although Injen has maintained a safe one, it's good to monitor it. When installing or handling the intake, be gentle with the 6061 - T6 aluminum tube to avoid any dents or damage. This will ensure the intake keeps providing a smooth airflow path and optimal performance for a long time.
