Using the Injen SP cold air intake is easy. First, make sure your engine is cool before installation. Locate the original air intake system and carefully remove it. Then, install the new Injen intake following the included instructions. Connect all the hoses and clamps securely. After installation, start your engine and check for any air leaks. When it comes to maintenance, regularly inspect the SuperNano - Web dry air filter. If it looks dirty, remove it and gently tap it to remove large debris. For a more thorough cleaning, you can use a specialized air filter cleaner according to the cleaner's instructions. Let the filter dry completely before reinstalling it. As for general use, avoid driving through deep water as it can damage the intake. If you notice any unusual noises or a decrease in performance, check the intake for any signs of damage or blockage.
