MY 2014 S550 - Spark Plug Replacement.
Hi all,
I need help replacing my spark plugs for a 2014 S550 4Matic. I can't for the life of me find which plugs I need for this car. Found videos of the W221 and the plugs needed for that model but can't find any for the 2014 version. Does anyone know if there's a guide written anywhere or know which spark plugs I need and how many? Also would you guys recommend, Bosh Iridium, NGK Iridium or Denso Iridium?
Thank you

On the 16 maybach I took out a plug at 50000 miles and it was like new. I put an entry into service book that I defer this job to a later date.

The car just passed 60k miles and it's a recommended service at 60k. I figured I wanna keep up with all the maintenance to keep the car running for a long time. I still can't find the bosh equivalent
