Using your Injen SP cold air intake is straightforward. First, make sure your engine is off and cool. Then, carefully install the intake following the included instructions. Once installed, start your engine and enjoy the improved performance. When it comes to maintenance, regularly check the SuperNano - Web dry air filter. If it looks dirty, it's time to clean it. You can use a gentle air compressor or a specialized filter cleaner. Make sure the filter is completely dry before reinstalling it. Also, keep an eye on the intake tube for any signs of damage or wear. If you notice any issues, contact Injen's customer service. And remember, this intake comes with a limited Lifetime Warranty, so take good care of it to make the most of that benefit.
