      Comments about NGK Nickel Spark Plug (DPR6EA-9):

      I used these spar plugs as direct replacements in my 2008 Honda Shadow Aero. It turns out these spark plugs are the EXACT ones used at the factory making them direct OEM replacements. I installed all four and the bike runs great. Just make sure they're properly gapped before installation and use a good gapping tool and a nice set of feeler guages to check your work.

              good replacement to the OE part. works very well without having to spend extra $ on Iridium plugs [which are obviously the best]
