Install the intake following the included instructions, using the Injen Twist - Lock System to attach the air filter. It's designed to be simple, so you don't need to be a pro. When driving, enjoy the increased power and performance. As for maintenance, regularly check the air filter. If it looks dirty, it's time to clean it. You can use a filter cleaning kit made for dry air filters. Make sure to let the filter dry completely before reinstalling it.
