Using the Injen Intercooler Pipe Kit is straightforward. First, make sure your car's engine is cool. Then, carefully remove the old intercooler pipes. Next, install the new Injen pipes, connecting them securely with the included silicone couplers and band clamps. When tightening the clamps, don't over - do it as it could damage the pipes or couplers. As for maintenance, regularly check the pipes and couplers for any signs of wear, like cracks or leaks. Clean the pipes with a mild automotive cleaner to keep them in good condition. If you notice any issues, contact our support team right away. Remember, this kit comes with a limited lifetime warranty, so you're covered.
