    The intake plenum (upper portion of intake manifold) has to be removed to gain access to spark plugs on right side of engine (towards firewall) ;
    You need lots of patience and be careful with all the connectors and small coolant hoses under it,it is fairly easy but takes time(labor time). Good luck, hope this info helps...
