Guys anyone got a link or info on if copper NGK's need to be gapped, and how you do that, i know this is such a stupid quesiton but I gota find out somehow

 

Factory Gap: .035-.044

 

I think they come pre gapped at .044.

 

Chapter 1, section 1-21 of the Haynes manual. Buy a wire-type spark plug gap gauge when you buy the Haynes manual and ensure the gap is set at 0.044" for the NGK BKR5E-11 copper plug. The Haynes manual shows 0.039 to 0.043", but thats for the BKR5ES-11 for the 3rd Gen Maxima. The Haynes manual specifies platinum plugs for 4th Gens as does Nissan.

 

I use NGK BKR5E-11 coppers and gap at .044"

 

I second that, just double check and make sure they are.

 

.039" to .043" per the Factory Service Manual.

 

I have not once gapped mine ... It's a good idea to check them but I still never do.

 

Never mind what I said. I appologize. I read the title so fast and what I read was "Proper plug gapping?" lol. The answer I gave is for the stock platinum plugs (which I would recommend actually). I can't answer for the copper plugs. I would assume the same gap but I don't want to give an answer based on an assumption.
