    Not as daunting as it looks. Remove battery, airbox and a few connectors.
    A good service manual/ rep-rom cd is worth the cost.
    I use NGK Iridium DCPR8EIX from www.beemerboneyard.com. Sometimes can find them locally.
    84K on originals?

    You will need the special tool to pull the coil pack off the plug. Other tools can damage the coil. A thin wall spark plug socket is also needed. 16 MM or 5/8" if I remember right. Bag and tag small parts and label connectors. Most fasteners are S/S so don't drop into unreachable places. Go slow and stop think act and review your work. At work we call this the STAR program.

    thought everyone had these.
    I take smartphone pics of pre work and various stages if it's not a routine job. The various plugs sometimes lay back in the correct position so not often a fear of mistakes.
