Using this intake hose kit is easy. First, make sure your vehicle's engine is cool. Then, remove the old corrugated factory inlet hose. Install the 4 - ply silicone hose from the kit in its place and secure it with the 304 stainless steel worm clamps provided. There's no need to calibrate the ECU, so you can start your vehicle right after installation. As for maintenance, regularly check the hose for any signs of wear or damage, like cracks or leaks. If you notice any issues, replace the hose promptly. Keep the hose clean to ensure optimal performance. You can use a mild cleaner to wipe it down, but avoid using harsh chemicals that could damage the silicone.
