So I ordered a box of NGK Iridium IX Spark Plugs BKR6EIX-11 stock number 3764. My question is, are these spark plugs pre-gapped? Otherwise I will have to gap them at .44? Running on stock engine with the exception of a new SRT intake that I will be installing soon. I appreciate your help.

I ordered mine form SummitRacing a few weeks ago. All came pre-gapped, but I double checked all of mine before putting them in... you should do the same.

Yup, pre-gapped. Don't drop them either.

I did mine as I just hit 60k and thought I had non-iridium plugs in my car, gas mileage was getting worse too.

After getting everything apart I saw that my plugs were iridium but were pretty charred up so I didn't feel bad replacing them. Smoother idle/acceleration, improved MPG, improved throttle response... I'm not saying it's the plugs(NGK) specifically. Most likely just the nice fresh plugs that helped.

So I just got the plugs in the mail and I could not tell if these plugs are ? gapped at .44? These are the BKR6EIX-11 stock number . These are already gapped and just want to make sure these are pregabbed at .44.

Thanks

I would check the gap, to make sure that they are at .44 :p


I just bought a set of Platinum NGK plugs. Should I get the iridium version instead?

Check where you ordered them, or take one out of the box.. I believe mine said Iridium on them. The iridium are supposed to be good for 90k miles before being serviced. It's not a difficult job but not exactly fun either, I'd spend the extra couple bucks to be able to put it off for an additional 30k miles.

To Nubel, go to your nearest automotive parts place and ask for a spark plug gapper(they usually have boxes of them sitting by the checkout lines), shouldn't cost more than $1 and is great to have in any toolbox.

Edit:
Here's a link to the set I ordered.

Go to an auto supply store. They have a thing called a gapper, its a flat circular piece of metal., it has numbers around the edges. It looks like a half dollar coin.

Good luck

So I just bought a gapper from autozone. I brought one of the plugs from home to work and the gap is at .41. I will check the rest of them later tonight. Is this gap ok? As mentioned before, I am running stock with the exception of an SRT intake going in soon and a header. What is the difference of different gaps if you were for example comparing a .30 gap to a .50 gap?

.41 will be just fine.

This the gap you are measuring, between the elctrode and the end of the plug:
