Using your Injen air filter is easy. Just install it in the appropriate air intake system of your vehicle as per the vehicle's manual. Remember to handle it gently to avoid damaging the filter media. For best results, check the filter regularly, especially if you drive in dusty or dirty conditions. When it starts to look dirty, use the Pro Tech air filter cleaning kit (part number X - 1030) to clean it. Follow the instructions on the cleaning kit carefully. After cleaning, let the filter dry completely before reinstalling. Don't use any other cleaning products unless recommended by Injen, as they may damage the filter or the special oil. Keep your Injen air filter in good condition, and it will keep your engine running smoothly.
