Ok I know I'm opening a can of worms but here goes my question. Stopped by my local auto parts store and asked for 6 x NGK BKR6E-11 2756 so I could change out my spark plugs in my 2013 GL1800 Level IV. I also needed a new feeler gauge to set the gap on the NGK's. The parts guys suddenly tells me, with the new spark plugs for sale now a days you don't set the gap any more because their is a resister inside the core of the plug that sets the right amount of spark, and if you try to set the gap that piece could break while setting it. Never heard of this, is it true? Just take the spark plug out of the box and install it, no gap setting required. What gives?????
