Using this Injen air filter is easy. Just install it in the appropriate air intake area of your vehicle according to the manufacturer's instructions. When it comes to maintenance, every once in a while, give it a light blast of compressed air to clean it. There's no need to oil it, so you can skip that step. As for precautions, make sure to check for any signs of damage during regular inspections. If you notice any tears or holes, it's time to replace the filter. Also, when cleaning, don't use too much pressure with the compressed air as it might damage the filter. Keep it in a dry place when not in use to prevent any moisture damage.
