I wondered this when I did my plugs apparently its a bit old Skool to talk about plug gaps these days
not had much petrol cars and don't normally keep a car long enough for plugs
however I have been told they are pre gapped throw away your gauges then.

Don't get me wrong, there has been some testing done regarding altering plug gaps on engines that have been extensively tuned/modded. But on a standard engine you won't notice any difference so isn't worth doing in my opinion.
Ure telling me, I got a gapping tool and feeler guage and popped the new plugs out of the box ... wtf ... pre gapped.
Yup that's what the master tech said when I got my update done as he asked about the condition of the plugs I had just done them and asked if the gap was pre set they were genuine plugs.
