Thanks for that 430..... I think as people with pulleys are not having trouble firing the IK20s with a gap of 0.44, and the OE gap is 0.40, I will get the IK22 for the cooler heat range, and regap them to be 0.40
This is a good read on sparkplugs ect

I would just use the IK-22's at the stock gap, they run fine. Messing with the gap on these iridium plugs is asking for trouble. One slip of the pliers or whatever you are using and you can break the delicate electrode.

the manufacturer Denso recommended the IK20 plugs which is a colder plugs than the IK16 that they manufacturer. However the IK16 based on reading is already colder than the stock plugs, so either one should work. As far as how they compare I have no idea. I've been lagging on getting this done...
What is the source that you came across that said the IK16 Denso plugs are actually colder than the stock NGK IFR6D10 plugs? I'm curious because after putting in the IK16's and reading through this post I'm a little less confident in the 16's. Help put my mind to ease.....

Something Slow
I looked further into it and I talked to someone at magnecor regarding the dielectric grease. m444 - you are definitely correct about the dielectric grease acting as a good lubricant. However, after talking to the dude at magnecor, I just crimped the boots a little more using long nosed pliers and they fit a hell of a lot better. Against the advice of magnecor, I also applied a very small amount of dielectric grease. All the wires have a nice discrete 'click' and the connections appear to be pretty robust.
AMGSC - I think the general consensus is that colder plugs are appropriate depending on a combination of your driving style (i.e. how you drive on the street and whether you track your car) and how much hp you have acquired over the stock hp rating. I forget how much you actually gained after your HPS SC (maybe 60-70?), but that would probably warrant a plug one stage colder. Then again, some of the guys here have put forth good arguments for why they haven't done this.

IK16 is hotter, IK22 is colder...

The engineers at Nippon Denso insist their IK20 is the equivalent heat range to our (C32) OE NGK IFR6D10. Their fitment guide http://www.densoiridium.com of course concurs. Don’t know if I gained any horsepower, but the placebo effect undoubtedly makes for a smoother running V6.
Congratulations on that 11.8 at 118. Takes some serious grunt to achieve those numbers.

I found a GREAT PRICE on the Magnacore wires $130 shipped ( gotta love the free ground shipping )

Sorry to bring this back up..but i need some help with decisions.
So....
here the thing im readind and thinking.
my car has now 41880 miles..dont think service B includes plugs and wires...
so i think i will need to get new plugs and wires...
from what im reading i should get IK-20's but not the magnecor wires....seem like there are a lot of issues.....
can someone help clarify this?
i will be also putting on the evosport pulley..
thanks in advance...

to answer your question, i would go with the IK22's they are one heat range colder than stock and will be better for you car in the long run...i am running the NGK version of this plug and i have had zero issues in 20,000miles!
i have these instock if you want to order them and i can supply the plug wires as well...
please let me know if you have any questions and i will be glad to answer them!
thanks!

The IK20 is the stock heat range for the C32 AMG. Some people go colder when they add more boost and switch to IK22 plugs (a step colder than stock C32 plugs).
For your car, IK22s are not the right plug. Check the W203 forum for the stock heat range. You dont have to use the Denso Iridiums though. You could use the NGKs.
and if you get new spark plugs, make sure you use the correct gap.

NGK Iridium IX is a type of NGK plug. There are different heat ranges for it. The NGK Iridium IX bkr6eix-11 is comparable to the Denso Iridium IK20 and the NGK Iridium IX bkr7eix-11 is comparable to the Denso Iridium IK22. I dont know what the number is for the comparable IK16 plug, but if they make it, judging on how those numbers just progressed after the "bkr," my guess is that it would be bkr5eix-11, but is just a guess. Check the NGK website and verify on the W203 forum with other C320ers. Also make sure that when you order the plug and install it, it is at the correct gap.

Recently replaced my ~102,000-mile '02 plug wires with (8) 112 150 01 18 & (4) 112 150 02 18 OE Bosch hardware.
Concurrently installed inexpensive NGK BKR7EIX-11s (gaped to .035”) in place of its former Denso IK22s.
Can’t be certain which ultimately contributed, although it’s running smoother and stronger than it has in a long while. ~$300 well spent.
