spark plugs

greyvan · 10-25-2009, 08:12 AM

When do they need to be change or when should they. Do I need a special tool? I have a 2001 E320 wagon,and they are difficult to get to.
Is there something I should know?

every 100000 miles. There is one key tool needed: a special boot puller spanner (you can get from ohlord). The rest are simple tools such as a 3/8 ratchet with a couple of extensions, and a slim 16 mm (5/8") spark plug socket with rubber insert. Torque value is 28Nm. Some people do it very with torque wrench, some don't. I consider it important to torque them to spec. Hope it helps.

Cheers

or 100,000 miles--it's in the owner's manual.

Use Bosch or NGK 7090 plugs with the single side electrode--do not use multi-tip or any other snake-oil plugs, according to ohlord.

greyvan · 10-26-2009, 06:13 AM

Thanks I didn't realize NGK was OKay. Are Bosch Platinum 2 OKay?

Franasia · 10-26-2009, 08:19 AM

is the correct Platinum plug for the M112 engine. Stay away away from the other Bosch Platinum types. There have been bad reports by other members in the past.

Cheers

greyvan · 10-26-2009, 08:48 AM

Thanks, I would assume that's the single ground type. Hey I see on your car it says E320S4, what does the S4 stand for?

anabase · 10-26-2009, 10:17 AM

NGK 7090 single-side electrode platinum plug.
.039 gap, use no anti-seize, they are bivalent plated.
$3 each, and they'll last 100k.

Or Bosch 7422, about 4 bucks.

You'll be needing the 17mm Mercedes boot tool. You can get one of these from Ohlord.

S is the designation for the wagon as the W is used for the sedan. So, S210 is a wagon and S4 stands for 4Matic wagon.

ohlord.

How can I buy the tool from you. I still have afew thousand miles left but I want to be ready!!!

ohlord · 11-17-2009, 02:47 PM

well past ready. The car is 8 years old and plugs were due to be changed 3 years ago.
Pm me for info

greyvan · 11-18-2009, 06:57 AM

Hi
I pulled a couple of plugs and they look just fine. My guess is someone changed them not to long ago, I got the wagon with 109k mi on it. I do have a pretty noticeable miss at idle, not really sure when moving along. What's a go way to locate the Problem? Is it common?
Help

ohlord · 11-18-2009, 10:44 AM

or at least the whole story.
Check the gaps. They could look fine and gap at 44tho.

greyvan · 11-18-2009, 01:35 PM

Hey,
What should the gap be? And if it is OK what would you look at next?
Thanks

ohlord · 11-18-2009, 08:21 PM

or .039tho in.
Toss in a can of seafoam brand injector cleaner into a half filled tank of fuel and drive till near empty then fill as normal with premium fuel.Never top off the tank.
