When it comes to maintenance, regularly check the Injen SuperNano - Web dry air filter. If it looks dirty, you can clean it using the recommended cleaning kit. This will keep the filter working well and maintain the intake's performance. As for precautions, always follow the installation instructions precisely. If you're not confident in doing the installation yourself, it's best to have a professional handle it. Also, keep in mind that using the intake in extreme conditions might require more frequent maintenance checks.
