Q: How to remove and install the air intake duct,Air Filter Box and resonator on a Honda Ridgeline?
A: Disconnect the PCV fresh air inlet hose from the Air Duct. Clearly label any other cables and hoses that are attached or connected to the Air Duct, then detach or disconnect them and set them aside. Disconnect the left end of the Air Duct from the air filter box. Loosen the hose clamp that secures the Air Duct to the Throttle Body. Remove the Air Duct. If you removed the Air Duct just to access some other component(s) skip this. But if you're planning to replace the Air Duct itself, or either of the small resonators attached to the duct, loosen the hose clamp(s) and remove the resonator(s). Installation is the reverse of removal. Remove the Air Duct. On 2001 and 2002 Acura and 2003 and 2004 Honda models, detach the cruise control cable clip from the air filter box. Remove the air filter box mounting bolts and remove the air filter box. Inspect the condition of the air filter box insulator(s). if an insulator is cracked, torn or otherwise deteriorated, replace it. Installation is the reverse of removal. The resonator, which is used on 2003 and later Acura and 2005 and later Honda models, is located below and ahead of the air filter box, in the void behind the left corner of the front bumper cover and in front of the left front wheel well. Raise the front of the vehicle and place it securely on jackstands. Remove the front bumper cover. Remove the side branch tube from the resonator. Remove the resonator mounting bolts and remove the resonator. Installation is the reverse of removal. For 2007 Acura models, remove the air filter box. Remove the battery. Remove the front bumper cover. Remove the left headlight housing. Remove the two clips that secure the small plastic cover and remove the cover. Remove the two resonator mounting bolts and remove the resonator. Installation is the reverse of removal.
