Spark Plugs; 273 engine; '07 SL550
My owner's manual is silent on the subjects of spark plug specifications and replacement intervals. Does anyone here have a link to info providing plug specs, replacement intervals, removal/replacement steps, etc?

The spark plug change interval is located in your maintenance manual page 54, (at 91k or every 5 years). If you don't have a copy I've attached one downloaded from mbusa.com.
As to the plugs themselves, see the attached EPC Ignition System parts list for part numbers.
Good luck,
Bob

Bob: Merci beaucoup for your post and its attachments. I do not have the Maintenance Booklet for my car, and this is the first time I've seen one ... quite informative. I appreciate your post, and I've bookmarked the link.
