Comments about Denso SKJ20DR-M11S Iridium Long Life Spark Plug:

I normally run NGK spark plugs but they were not in stock. These are the exact replacement for the factory installed NGK's that came in the Civic. No issues. They come correctly gapped from the factory. Installed without issue and car runs fine.
