After some search
I feel confuse between these 3 types of NGK

- Ilkr8e6
one member use it with good result
It is evo X spark plug

- sizkbr8a. 8hs , its BMW alpina b7 plugs
One member states that is renntech plug

-Ngk 6706 or Lkar8ai-9,
One member tried it, after consulting with NGK
I think its similar to sls oem plug, ngk ilzkar8a-10

Anybody can help ?

If the stock plugs for the 156 are 0041593903 or NGK ILZKAR7A10 then we should be able to use 1591590003 or NGK ILZKAR8A10 for anything with around a 100hp tune?

It looks like the Denso equivalent is their 3457 FXE24HR11 < 0.01mm larger gap on that one.

I paid the Benz tax and went with Weistec just to be safe. If it works for them with all the mods they do, they will work for me with my tune only car.

It looks like the Weistec have a silver centre electrode and the nickel/zinc side electrode. This would have an ever so slight performance edge over the iridium plugs at the expense of only lasting about 1/3 as long.

They are one step cooler than standard so about NGK 8, Denso 24 or Bosch 4

Just bought two sets.

I know indexing in a 4 valve hemi without direct injection and a central spark plug is probably a complete waste of time but I guess we just don't want the side electrode pointing directly towards the intake? ie. fire the flame front up wind across the intake valves with the side electrode towards the exhaust side to get the longest throw?

Hello,

Here is the recommended product, it does require our specialized spark plug socket to install:

Isn't this thread about the C63 AMG W204? Where did the M157 come from? Seriously.. It's M156; ya got me clicking onto the links and then I just happen to see the M157 plus the tip of those plugs..

Kinda stuck with this... I wonder how they are going to be like...

No its actually about the M157 you are in the W218 section.

There is a thread on the W212 E63 page about plugs, and I remember the conclusion being that OEM is best. Better than all of the rest.

Brisk qr12ls and mr12s both work and have different benefits. Biggest thing is to have a high energy plug with a tighter than stock gap. All misfire issues stem from spark blowout under high cylinder pressures. Look for the thread in w212 forum. I posted tons of info there.

iglambo

The number of the plug is yr5ni332s just you need a thin wall tool to install it.

if you want to blow your engine use brisk
my engine was badly damaged because of them
the plug broke

Listen man, you have posted this a few times. Plugs don't fail like that structurally. You had a lean condition or detonation that took the electrode off. This isn't a problem with the plugs, and isnt uncommon on tuned cars making long hwy pulls like you were when you lost that cylinder. Just deal with it as a fact of life when tuning boosted motors.

mjd222

Maybe your right
But i check I found Ford F-150 had ton of problems whit it brisk
And wisetech as I know the old plugs from brisk and changed to Bosch
As a company they don't change an less the old one had problem

^^^Ive burned through a bunch of plugs running Wiestech tune...Stock and there plugs. Like stated already detonation more then likely did that.

The old weistech plug was brisk
But the new one is made by Bosch
Because of the change Quality issue

Bringing back an old thread. I have a 13 CLS65 PP with Renntech tune on it. Just approaching 46k miles and on 2 occasions recently Ive had an issue. Under hard acceleration and arond 120mph, the engine would start bogging and vibrating feeling like a wheel out of balance with the CEL coming on. I immediately pulled over and when in park, it sounds like the engine misfiring. Shut it off, restarted and all is well with no codes thrown. Happened a second time yesterday under the same conditions and remedy. What could be the isssue? Is it a bad spark plug? When should they be changed and what plugs are reccommended. According to my reciept( I am the 2nd owner and the tune was present already) R Performance BiTurbo plugs were installed by Renntech on 4/2013 at around 20k miles. Any help will be appreciated.Thanks.
