Using your Injen air filter is easy. Just install it in place of your old air filter following your vehicle's manual. It's important to note that while this filter is very durable, avoid touching it with dirty hands as it can affect its performance. For maintenance, check the filter regularly, especially if you drive in dusty or dirty conditions. When it gets dirty, use the Pro Tech air filter cleaning kit (part number X - 1030) to clean it. Make sure to let it dry completely before reinstalling. This will keep your filter in top shape and your engine running smoothly.
