Definitely worth your while to research the CORRECT, RECOMMENDED torque spec for your specific application. Make sure they’re each gapped to spec. Many plugs come “pre-gapped”, but double check for accuracy to be sure. Check the bottoms again in 500-1,000 miles, make sure they’re NOT burnt toast! And +1 on the anti-seize. A dab across the threads down one side will do it and yes, it magically gets everywhere. It remains an unsolved phenomenon!!
