Using your Injen EVO1106 Evolution Air Intake is easy. First, carefully follow the installation instructions that come with the kit. Since it uses the Twist - Lock System, the installation process should be quick and straightforward. When your car is running, the intake will draw in more air, giving your engine extra power. As for maintenance, check the SuperNano - Web Dry Air Filter regularly. If it looks dirty, you can clean it according to the filter's cleaning guidelines. Make sure all the clamps and couplers are tight at all times. If you notice any signs of damage to the hardware or the filter, replace them as soon as possible. This will keep your intake working at its best and ensure your BMW E46 M3 performs well for a long time.
