To service the air intake duct and resonators, it is necessary to unplug the electrical connector of the MAF/IAT sensor for the model till 2010 and the BARO/IAT sensor for the model 2011 and onwards. Following that, unbend the hose clamps at both sides of the air intake duct and take out the duct and the reassembly process is in the similar manner with the disassembly. Regarding the air Filter Box, start with the air Filter Box cover and the filter element before removing the air Filter Box mounting fasteners if your model is 2006 or later. Finally, take out the air Filter Box, with installation also being the reverse of removal.
