C63 M177 - Stage 2 Tune - What Spark Plugs?
Hi all,
I am now running a decat with Stage 2 tune on my car:
The spark plugs are 'old' (10k miles) and need a change to help with the new tune.
Any recommendations on what plugs to use?
Are there any 'step colder' plugs that work well with a stage 2 tune?
Thanks

I am no expert on this, just wondering the same thing myself. My tuner, EC Stage 2, said that factory plugs were just fine and they have 20,000 miles on them. I think I will pull them and take a look.

I'm about to change my spark plugs as well.
Does any one know the correct part number for oem plugs? Maybe colder plugs as im on euro charged stage 2? Do oem come pre gapped @ .025?
As for oem is this the correct plug?
000-159-05-00
EDIT
I just talked with MB over the phone 000-159-05-00 is the correct part number for oem plugs.

Champion 7600
This must be the one!
Champion Double Platinum Plug Number KEC4PYPBF-1 Spark Plug
- Heat Range: 4
Champion 4 is NGK 9
**Unfortunately** these Champion plugs have 14mm thread and are matched according to Champion website.
This Champion 7600 is one step colder if in fact the stock plug is NGK SILZKFR8F7S which the same heat rating for Champion 9069
Champion Iridium Plug Number KEC6WYPB-1 Spark Plug
... and BRISK QR12LS
.
Searching NGK website I found...
NGK 93253 R2556G-9 Racing Plug
I inquired with NGK to find out if these or another one step colder plug works, and also if ignition coils need to be swapped for these plugs.
If I get a response I'll update.

PTG is using HKS Racing Plugs designed for Nissan GTR.
I'm not there yet. I'll give these a try after I install Pure 900.

We also haven’t seen the need to upgrade plugs until going larger turbo. We run them on our setup and believe they helped with some hiccups during WOT shifts.

Just check that it's not caused by coil packs. Have you had the coil packs changed since owning the car? If so, you can rule that out.

OEM plugs are fine for Stage 1 but anything higher upgrade to HKS plugs. I'm using HKS plugs for the last 2 years after turbos were upgraded, 26psi and they're running strong.

The misfire has only happened once and I was on the track when it happened, about 3/4 through my session.

. MB Dealership replaced Coil Pack 5 and 6.
. NOTE: Coil Packs are warranty by Dealership till 100,000 miles. So no charges. They had my car for a long 2 weeks
. I also noticed they replaced a spark plug which may have been installed incorrectly.
