Using your Takeda intake is easy. First, make sure you have all the parts included in the package: tubing, filters, couplers, and hardware. Then, follow the instructions to install it on your 2008 - 2017 Mitsubishi Lancer. When using, just drive your car as normal, and the intake will do its job of maximizing air flow. As for maintenance, the Pro DRY S air filter is low - maintenance. You don't need to use any oils on it. When it gets dirty, simply clean it with soap and water. Let it dry completely before putting it back in. Remember to check all the connections regularly to ensure there are no loose parts. If you notice any issues, like reduced air flow or strange noises, it's a good idea to have it inspected.
