Vehicles nowdays are made with minimal tuning requirements except for the spark plugs, oil and filter changes. Most things are controlled by the PCM and requires no adjustment or unadjustable.
However for your model, replacement of the spark plugs requires the intake manifold to be removed to gain access to 3 of the plugs.
Attached is a diagram for the removal of the ignition components, do only the necessary and follow the numered sequence.
