Vios 1.5G with 1NZ-FE engine? The spark plug's gap specs is really 1.1 mm.(both Denso and NGK), and not .08mm.
Arch, where'd you find that info? The car's manual states 1NZ-FE engine's is 0.8 mm spark gap (p.161) Well, either way, would you know if what would happen if we used a different gap size for the engine?
