I've done most of the maintenance on my vehicles for many years. However when recently I changed the plugs in my 2000 Box S I had 2 plugs where the ceramic insulation cracked. That results in a low speed miss that goes away after accelerating past 3K.
Is spark plug quality going down? The 2 victims were NGK and Beru. Am I getting too strong? That I doubt. When I installed them I used a torque wrench and went to (I think) 22ft. lbs. and it felt about correct for that torque measurement. For the future I'll go back to snug and one tug (which is probably around 16 ft. lbs.). Anybody else experience this?
