Using this Injen air filter is easy. Just install it in your vehicle's air intake system following the standard procedures. When it comes to maintenance, if you notice a drop in performance or the filter looks dirty, you can clean it with a light blast of compressed air. This helps to remove the dirt and debris that has collected on the filter. Remember, this filter doesn't need oil to work properly, so avoid oiling it as it can lead to problems with your MAF sensor. Keep an eye on your engine's performance and check the filter regularly to ensure it's in good condition. If you have any doubts or encounter issues, it's best to consult your vehicle's manual or a professional mechanic.
