You bought spark plugs from Nissan? Yeah, you should make sure they are properly gapped for your engine.

depending on which ones you buy, they will be pre-gapped. im not sure which ones you use but if you take the ones we use for an altima for example, bkr7-11, the 11 specifies that its gapped to .043" or 1.1mm. likewise, a plug with a -9 would be .9mm or .035" and so on. if i didnt confuse you, i hope this helps out...
if you have the number from the spark plug and its an NGK, this should help you out.

The OEM plugs were NGK PLFR5A-11 which were factory set to 0.044mm. Is this the right gap or u need to reset this to ???. I also wanted to what is the standard GAP required for these models.

check the data plate underneath the hood... it should have that info there...

ok... according to the fsm, the gap, using plug: PLFR5A-11 should be 1.1mm or .043". according to the fsm, that is also a platinum tipped plug.
you can get your copy of the fsm here.

thanks buddy, i just realiseda typo error on my mail, it is 1.1mm. Great ! will start working in tandem with the FSM requirements.

FWIW, a .44 gapped plug won't make any difference versus a .43 gapped plug.
