Find the coil packs for each cylinder. Remove the plug and install the new ones. The ignition coils are the black gadgets that have an electrical connector to it and are bolted onto the intake manifold with a small nut. The spark plugs are pretty deep into the engine head. Be careful when threading in the new spark plugs because these engines have aluminum heads with aluminum threads which can be easily damaged if over torqued.
