Open the hood and locate the air box assembly and air intake tube on the driver's side of the engine. Disconnect the intake air temperature (IAT) sensor located on top of the air intake tube by lifting up on the retaining tab and then pulling the wire harness off the sensor. Disconnect the massive air pressure (MAP) sensor wire harness from the MAP sensor located on top of the air intake tube. Use the slotted screwdriver to loosen the band clamp from the air intake tube attached to the air box housing. Loosen the band clamp on the other side of the air intake tube attached to the air intake tube, which is attached to the engine. Use your hands to remove the air intake tube from the air box and engine as a complete assembly. Set the air tube, IAT sensor and MAP sensor assembly aside so no damage will occur to it. Disconnect the two upper air box release tabs of the air box by flipping them open by hand. Pivot the air box cover downward. Then lift it off the retaining tabs at the bottom of the cover to remove the cover from the air box. Remove the air filter from the air box. Inspect the interior of the air box and remove any debris by hand (if excessive, use a shop rag). Insert the new replacement filter into the air box. Then align the air box cover's lower retaining tabs to the slots in the air box housing. Pull the cover up and reattach the two upper retaining clips. Reinstall the air intake tube assembly. Be sure to align the rubber notch of the air box side with the rubber tab of the air intake tube. This alignment will place the upper sensor connections in the proper place. Tighten the band clamps on either side of the air intake tube assembly with the screwdriver. Then reconnect the IAT and MAP sensor wire harness connections.
