NGK IX Part number for the CLS, BKR6EIX-11 or ZFR6FIX-11 !!!
I emailed NGK tech support for the correct part number for the CL-S.
Here is their answer:
Checking with the EUT forum The IK20 equivalent is listed as: BKR6EIX-11
So which one is the correct one?
Checking with NGK decoding pdf, it seems that BKR=== FR but I do not know about the Why FIX "Special feature code" instead of EIX.
Here is their answer:
The spark plug you need is a ZFR6FIX-11 stock number 6441.
So which one is the correct one?

More info about "Projected Spark Plug":

Therefore, I understand that the "Projected NGK Irdium Plug" is the High performance version
Projected Core Nose: This type sticks the spark 1/8" into the combustion chamber. This helps prevent low speed and cold fouling and also gets cooled by the incoming charge at high speed. It is difficult to build a projected plug in very cold heat ranges however, because of the long ground wire, which is typically the hottest part of the plug. To a very limited degree, this plug behaves as though the ignition were more advanced, because it places the flame more centrally in the chamber.
