Plug Gap

[slvryaris]

Bought the NGK IFR5T11 plug and it says on www.sparkplugs.com that the OE gap is .032 but the service manual says it needs to be between .039 and .044 so did I need to make this gap bigger and why does it say that the OE gap on the NGK plug is .032 and some of the others have .035 and .044 ??

I thought the OE gap beside the plug on that site is what the factory gap should be on that specific car and not what the gap is on that specific plug is ..

Just found my gapping tool buried in my tools. The NGK plug is measuring dead on .040 or just a tad bigger. So the OE gap on that site has me totally confused so I am guessing these are pre gapped for the car since it is within .039-.043 like the manual states. I have always bought plugs pre gapped so this is why I am having so much trouble plus I dont want to blow it up.
