Using this Tomei silicone turbo inlet hose is straightforward. First, make sure your vehicle is turned off and cooled down. Remove the old hose carefully. Then, attach the new hose using the included clamps and hardware. The adapters provided will help it fit different models. As for maintenance, regularly check the clamps to ensure they are tight. Look for any signs of wear or damage on the hose, like cracks or tears. If you notice any issues, replace the hose promptly. Also, keep the hose clean from dirt and debris to maintain its performance. When the turbo is under high load, the hose can handle the pressure well, but always drive within safe limits to avoid unnecessary stress on the components.
