Using your Injen oiled air filter is simple. Just install it in the appropriate place in your engine's air intake system following the standard installation process for air filters. When it comes to maintenance, check the filter regularly for dirt and debris. If it looks dirty, you can clean it using the Pro Tech air filter cleaning kit (part number X - 1030). First, remove the filter from your engine. Then, follow the instructions on the cleaning kit to wash the filter gently. After washing, let it dry completely before re - oiling it. Remember, don't over - oil the filter as it can cause issues with your engine's performance. Keep it in a clean and dry place when not in use. And always handle the filter with clean hands to avoid introducing extra dirt.
