Using this intake hose kit is straightforward. First, make sure your vehicle is turned off and cooled down. Locate the factory corrugated inlet hose and carefully remove it. Then, install the 4 - ply silicone hose that comes with the kit. Use the 304 stainless steel worm clamps to secure the hose in place. Attach the brackets and zip - ties as needed. There's no need to calibrate the ECU, so you can start your car right away after installation. As for maintenance, regularly check the hose for any signs of wear or damage. If you notice any cracks or leaks, replace the hose immediately. Also, keep the clamps tight to ensure a good seal and optimal performance.
