Using your Injen air filter is easy. Just install it in your engine's air intake system following the standard procedures. When it comes to maintenance, keep an eye on the filter's condition. If it looks dirty, use the Pro Tech air filter cleaning kit (part number X - 1030) to clean it. It's 100% cleanable, so you can reuse it. As for storage, keep it in a dry place away from direct sunlight. Also, make sure to follow the installation instructions carefully to ensure proper fit and performance. This will help your engine run smoothly and keep it protected from dirt and debris.
