Does anyone know the spark plug torque settings and gap size for a Skoda Octavia 2012 1.4 tsi elagance the plugs are ngk please 

30Nm, careful because a lot of torque wrenches won't be accurate that low. The plugs should be pre-gapped when purchased. 

Pre gapped when purchased.  But still check the gap of each.  Just incase some person already had it out of the box and took off the protective tubs and knocked it.  Or you do before fitting.    Not uncommon.

On the box just says tighten down then a half turn to 2 thirds
