First you need to find the spark plugs! No, really! I have tinkered with engines on several cars, but I cannot see the plugs or leads on my 406. I haven't looked too hard, just a cursory glance whilst checking the oil level, etc. Are they hidden under a cover somewhere? If anyone can shed some light, I would be obliged. Thanks. Answer; They are located within a single bar located beneath the rocker cover. 1) Remove the silver rocker cover, 8 turn screws 2) you will see the spark ber beneath held down by 3 x 5mm bolts 3) Undo the 3 bolts an lift the bar off, there will be 4 rubber cups that connect to the top of the sparkplugs, you will see the plugs located within tubes, so a long wrench is required. Its not as fiddly or difficult as it may sound, just done mine and with the right tools will take approx 15 or 20 minutes to do..
