Using this COBB intake tube kit is a great way to enhance your 2022 - 2025 Subaru WRX's performance. First, when installing, follow the included installation guide carefully. Make sure to properly attach the tube between the factory airbox and the turbocharger inlet using the provided black 5 - ply silicone couplers and clamps to prevent any air leaks. Since the factory airbox has a hydrocarbon trap, don't remove it as it's required for emissions compliance. During normal use, keep an eye on the tube and couplers. If you notice any signs of damage, like cracks or loose connections, it's time to check them out. To maintain the tube, you can clean the wrinkle black powder - coated finish with a mild soap and water solution. Avoid using harsh chemicals that could damage the coating. This will help keep your intake tube in great shape and ensure your car runs smoothly.
