I have a 2015 AR210, twin MR-1 engines…spark plug tip. Looks like the torque spec based on this forum is about 9.5 foot pounds. I set my small inch pound torque wrench to 120 (10 ft lbs) and found that after bottoming out with finger tight tension, one more half turn is just right, in case you don’t have a torque wrench or are swapping out a plug on the water. I was using NGK brand plugs. Hope this helps!
