I just bought a new set of OEM spark plugs (NGK P/N 7969) for my 2.8 30v, and like an idiot I forgot to buy a new gap tool after I lost my old one. Do OEM plugs come pre-gapped?

Thanks in advance!

 

They're "supposed" to come pre-gapped, but I've never seen a set that was actually right. You definitely need to gap them yourself.

 

Alright, that said, how would I go about gapping double grounded plugs?

 

I don't think you gap double grounded ones..

 

Now I'm confused, should I, or should I not gap these? Here is a picture of one:

 

Incidentally my last set of plugs (NGK BKR7E) were all pre-gapped right at 0.032". I just left them, but should probably drop the gap down a bit... (though my ECU hasn't reported misfires).

OP: I'm not sure the dual-electrode plugs are intended to be gapped by the user.

 

After a quick google search I found that, No, you do not gap them. They come pre-gapped.

 

Yeah, I popped them in and the engine is running fine, thanks for the advice

 

Ahh, my apologies. I didn't look up that part number before commenting. I didn't realize they were double grounded when I made my earlier post. Well done not listening to me lol
