I am putting new plugs in my Yamaha 115 4 stroke. Here where I work we have NGK plugs which is what I want but according to all I read, my motor needs the LFR6A-11 but all we have here are the LFR6A with no -11 on them. After researching this, I think I find that the 11 on the end is the gap of the plug, as I have compare everything else and it seems to be the same. Just wanting to get a second opinion or other info on this before I make a mistake and screw up my motor. Any info greatly appreciated
