Using the Perrin Black Turbo Inlet Hose is easy. First, make sure your vehicle's engine is cool. Locate the existing turbo inlet hose and carefully remove it. Then, install the new Perrin turbo inlet hose in its place, ensuring a proper fit. You don't need to tune your vehicle after installation, and it should take about 3 hours to complete. When it comes to maintenance, periodically check the hose for any signs of wear or damage. Keep it clean from dirt and debris. In case of any issues, the 5 - year manufacturer warranty has you covered. If you're upgrading your turbocharger, it's a good idea to install this inlet hose at the same time to make the whole process smoother.
