NGK has the angle torque for the different seat types on the box - conical seat is 1/8 turn after contact, washer type 2/3 turn. Both feel “nice and snug”, so that’s good enough for me, and the techs & engine builders I’ve worked with for 20 yearsWait, y'all torque your spark plugs to spec?
So nice and snug isn't good enough
Perfect. If it's a clicky type, make sure you store it as the manual says.Thanks for the response. Picked up Icon 3/8 5-80 ftlbs.
