To remove the air intake duct and resonators, start by removing the engine cover and disconnecting the Positive Crankcase Ventilation (PCV) fresh air inlet hose. Then, loosen the hose clamps at both ends of the duct and remove it. If you're replacing the duct, remove the resonators and install them on the new intake duct. When taking out the Air Filter Box, start by taking off the housing covering and the filter element, and mounting bolts. Remove the housing. To perform an installation, you can simply follow the exact opposite steps that were taken during the removal process.
