What are NGK's gaped to out of the box, can they just be left alone safely?

Yep, they seem to be gapped perfectly for the LNF right out of the box. I noticed the same thing when I went to gap mine as well. I thought it was a lil closer to the .030 mark but thats what I get for using a spark plug gapper to check the measurement. Shoulda pulled out the feeler gauge.

I just bout 41-108 from O Reilly and they came .030 out of the box, so I regapped them to .035 . Regapping was a PITA. I'm on stock tune no mods.

when you change spark plugs do you have to torque them to a certain ft/lb?

no. larger gap creates more power. larger spark is more power. but like someone said. gap to much and u get misfires.

I don't know the ft/lbs off the top of my head. I measured the resistance as I took them out and went off that. Not the recommended way, just don't overtighten them or it's big bucks to get them changed the next time. I also used dielectric grease in the coil pack & on non coil side of spark plug to help with corrosion. Went off a post I found on this site

Something to keep in mind guys, .032 and .32 is not the same thing. If you see a two digit spark gap measurement, that is Metric. Three digit refers to Standard. Pay close attention, it's very easy to get confused. So... .032" actually is equal to .88mm (may be why so many people have idle issues, everyones getting mixed up in standard and metric.)
