Hello all, likely a dumb question, but I'm new, so... I have reviewed FAR part 43 regarding preventative maintainance allowed by owner/pilot. Specifically it indicates that removal/cleaning/replacement is allowed with the normal owner/pilot requirements of other preventative stuff. However, I was wondering if "replacement" means replacing the plugs that were removed, or does it include replacing with new? I would have assumed the latter but some searching led me to a forum in which at least one person said that removal/cleaning/gapping/reinstallation were allowed, but actually replacing the existing plugs with new was not. Again, amateur league question but I was looking at doing this on my 182 and don't want to run afoul of the regs (afoul...plugs..see what I did there...). Thanks!
