As for maintenance, regularly check the SuperNano - Web dry air filter. If it looks dirty, clean it according to the instructions that come with the filter. Also, inspect the intake tube for any signs of damage or wear. Avoid using harsh chemicals on the intake. And remember, this intake comes with a limited lifetime warranty, so keep your purchase details handy in case you need support.
