Using the Injen Intercooler Pipe Kit is easy. First, make sure your engine is cool before starting the installation. Remove the old intercooler pipes carefully following the car's service manual. Then, install the new Injen pipes in the same place as the old ones, using the provided silicone couplers and band clamps. Make sure all connections are tight to prevent air leaks. When it comes to maintenance, regularly check the couplers for any signs of wear or damage. If you notice any leaks or the couplers seem loose, replace them as soon as possible. Also, keep an eye on the pipes for rust or dents. Wash the pipes with a mild soap and water solution occasionally to keep them clean. Remember, this kit is designed for specific Dodge Dart models, so don't try to use it on other vehicles. And since it comes with a limited lifetime warranty, if you have any problems, reach out to Injen for support.
