| Let me explain something before you
start reading and looking at the pictures. I did a ton of engine
work, all bundled together, it included valve cover gaskets, valve
cover painting, valley pan, intake gaskets, spark plugs and on and on,
so some of the pictures will show colored valve covers and that's
because I take pictures as I go and some of them get tossed because of
clarity!

Tools:
Ok, let's get started.

First
remove the acoustic cover. Push these 4 plugs in and pop the cover
loose: |
 |
|
Now take a flat
head screwdriver, pop these little covers off and remove the 10mm
bolts that hold them on:
|
 |
|
Now that those
covers are removed you’ll be staring at the bremi coils and below
those bremi coils are the spark plugs. So first things first, remove
the plugs that sit on top of the bremi coils. To do this simply slide
the metal tab with your flat head screwdriver and pull them off:
|
 |
|
Now label each
one of the bremi coils so you can put them back in the same location
they came from. You don’t want to mix these up, so label them! Take
a 10mm socket and remove the nuts on each side and finally pull the
bremi coils off. NOTE: You may have to pull the bremi coils with
some force: |
 |
|
Now that those
are out you can remove all 8 spark plugs. Yes 8, it is an 8 cylinder,
4 on each side…….Ha-Ha-Ha. With the spark plugs removed you can see
some of the pooling oil, um yeah, that means Valve Covers need
replacing! I did this in my major maintenance, but I am splitting
this up for instruction purposes:
|
 |
|
And some oil
pooling on the other side, oddly enough, the pooling was isolated to
the rear most spark plugs on each side facing the firewall:
|
 |
|
Minus the plugs
that had some oil on them, the other plugs looked pretty dark and were
definitely due a change: |
 |
|
Here’s the 2
plugs that had oil pooling, not the worst I’ve ever seen but it was
only going to get worse:
|
 |
|
I pulled NGK’s
out and they were the original, everything I have read and in talking
to the parts department it sounds like BMW is recommending these Bosch
plugs now. All seems well since I put them in, and I’ve been driving
with them for about 14,000 miles so far: |
 |
|
New Plug end,
shiny:
|
 |
|
No question on
torque specs here. The package said 21 ft. lbs. and that’s what I
torque’d them to, all seemed good:
|
 |
|
Ok to finish up
put a dab of anti-seize compound on the plug and rub it around the
threads prior to putting the plugs in, this will help you out when you
go to change the next time. |
 |
|
Put the 8 plugs
in and torque to 21 ft. lbs., reinstall the bremie coils and bolt them
down.
|
 |
|
Finally put the
plugs on the top of the bremi coils and reinstall the covers. You’re
done!:
