Got a question for those of more knowledge than myself

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

Its not the gap, it codifies special electrode distances

Just another thing...

Check the gap on all of them before installing and set it to OEM specs. The gaps were all different out of the box on the last NGK plugs I installed.

That applies to any plugs out of the box. I used to do tune up in a service station years ago and most of them had to be re-gaped because banging around in the box will bend them a little and that's all it takes to mess them up

Yes, plugs do not come pre-gapped
