First you need to remove the passenger seat. Then look for the cut out in the carpet that will let you have access to bolts to remove the access panel to the plugs. It sounds worse than it really, is the carpet that you have to pull back has sections of velcro to keep it together so look for that before removing any interior panels. If your doing a tune-up this will be easy as compared to the cap and rotor replacement.
