Remove the plastic cover and you will see the coils. Remove connector from all coils. Remove the bolts holding down coils. Pull up on coil to remove. You will feel some resistance because the spark plug boot is attaced to the bottom of the coil. Remove spark plugs and replace in reverse. Heres a you tube video of someone replacing the spark plugs in your type of vehicle. I must warn you to turn off the speakers on your computer. The song isnt to pleasing.
