When you start the engine, you'll notice the difference in performance and sound right away. For maintenance, check the Injen SuperNano - Web dry air filter regularly. If it looks dirty, clean it according to the filter's cleaning guide. Avoid using harsh chemicals on the intake tube or filter. Keep the intake away from water as much as possible. If you live in a dusty area, you may need to clean the filter more often. Remember, this intake comes with a limited lifetime warranty, but proper use and maintenance are important to keep it in good shape.
