Plug gap size
 

Can anyone help with the plug gap setting for my SL using NGK DCR8EIX plugs

Thanks in anticipation

Most folks fit NKG DPR8EA-9. These are the normal version of the iridium ones you've fitted and come pre-gapped at 0.9mm (36thou), although the manual specification is 0.6mm (24thou). The igntion system is well capable of firing the bigger gap which is less susceptible to plug fouling.
