Spark Plug Change
Just FYI...apparently changing the spark plugs on these cars is a pain in the a$$. As someone recommended here I had it done with my (early) 15,000 mile service, and the plug change alone took 6 hours of labor, +/- $500 cost. Hope it was good preventive maintenance

Factory procedure is to remove the rear bumper and heat shields, remove the intercoolers, remove more heat shields ...
then time needed to realign the shields precisely afterwards or escaping heat through open seams can melt the bumper..
I'm having plugs changed on my MBZ today as part of yearly maintenance - 16 plugs ( 2 per cyl) and pulling off the fuel injection and shrouds and shields etc. there and it'll be almost $600 for that alone !

I was interested in doing the spark plug change over the winter also. Loren (Renntech) says in his procedure, that you do not need to remove the rear bumper - but I'm not clear if the directions are for a TT or a NA 996. Has anyone done the plug change without removing the rear bumper?

The bumper doesn't HAVE to come off but it is a bit easier to access the plugs with it off and removing the bumper (on the lift of course) isn't any big deal. (Regular 996NA is cake, no bumper off or exhaust.)

Ken, I need to know the tools you used to do it without removing the turbos. I may have to go back in there to check a plug.

remove the bumper, intercoolers and remove heat shield fasteners and carefully bend the heat shields out of the way, at this point you will see the coils, upon reassembly rebend the heat shields to their original position
Be careful not to strip the coil allen fastener heads
It is tedious but not all that difficult, a lift helps tremendously
