Best Answer

Take plastic covers of each side to expose coil packs

Loosen but don't remove rear drivers side bolt and front passenger side bolt from top of plenum chamber.

Remove remaining plenum chamber bolts (this way you don't have to replace gaskets.

You'll have to chock up plenum chamber to get to two of coil packs that have to be removed to expose plugs

Remove single bolt and carefully pull out coil assembly

Remove spark plug using an extension tool as they're buried quite deep
