The Gap specification is 0.035 for the 4.0L engine, and 0.040 for the 4.7L engine, good-luck!!

Are NGK spark plugs pre-gapped?

As far as I know, they all are. You can buy a real cheap gap checker at a parts store counter-they only cost about a dollar, and people should always check the spark gap, even on pre-gapped plugs just to be sure.
The correct gap should be shown on the Vehicle Emissions Control Information sticker-the VECI label that is under the hood-a white sticker label.

What is the correct spark plug gap?

Most cars have different spark plug gaps but can be the same in some cases. Under the hood of your car will be a white sticker around the radiator or shock tower area that will have information about the engine size, the car year, most times spark plug gaps, and other emission related things. If you do not find the spark plug gap but do find the engine size (written as liters - ex: 2.5L), call any parts store and they can give you the plug gap for your engine/car.

I need the fireing order for my ford bronco its got a 351 its a 95 i need a the gap for the spark plugs *** well

The firing order on the 351 that came in the 1995 Bronco is: 1-3-7-2-6-5-4-8
The spark plug gap should be on the emissions sticker under your hood, usually on the radiator support. It may also be on the underside of the hood.
If you cannot find the sticker, try a .044 gap, if that doesn't work go a little higher to a .052.

Spark plug gap1999 suburban with a 350

Look under the hood, there should be a white sticker with the spark plug gap. The sticker will have a bunch of information on it, It should say something like this vehicle conforms to all 1999 emissions control laws, or something like that. Look at the corner of the top of the sticker and it will have .045 or could be all the way up to .060, or it could be listed farther down on its own line under the emissions info. That is your spark plug gap. Now, if the vehicle has been in a wreck and the front end has been replaced, it might not have a sticker, or the sticker it does have is for a smaller or larger engine. In that case, three different options: look in your owners manual, pull a plug and check the gap on one thats in there, or what store you buy the plugs at should be able to give you the gap for your vehicle. Hope this helps

Spark plug gap

Look under the hood, either on bottom of hood or near radiator, the proper gap for your vehicle should be on the emissions info sticker (white sticker about 3" x 4").
