Just bought NGK spark plugs got questions
I just bought the NGK spark plugs from rx7.com and it says that the gap for a RX-7 is 1.1-1.7mm, but if you look at the plugs they look differently. Do you think they are already gapped and ready to put in. I also got the High performance NGK spark plugs and they came out of the box with 2 together and 2 seperate. Which ones are the trailing and which ones are trailing. I plan on putting them in this weekend so help please.

yeah, they come pre-gapped. also the lower number (heat range) = leading plugs (lower holes)
that was to quote a forum post made today...do a little research

Alright, I'm "MazdaSpeed93"'s friend with a GST. I've never touched a rotary engine before but I took up the task to change the plugs and wires without anything to go by. I got it all done and I have two 9's on top and the two 7's on the bottom. Left goes to the top left, top middle goes to the bottom left, bottom middle goes to the bottom right, right goes to the top right. I'm 99% sure that's right, I just want to make sure.
Now, when we started it up, there's hesitation/missing. All the gaps on the plugs were about 1.4 when I checked them out of the box, so I left them since it says 1.1-1.7 is good. But the plugs that were in there before looks like they had a smaller gap. I don't think that small of a gap difference is going to cause the car to run differently, but what do you think? And yes, all hoses, electrical plugs, bolts, intake gasket were put back on. It's not a huge miss, just enough were you can tell.
BTW, he only starts it up about every two weeks because it's in storage and it smokes like a MOTHER when he does. Then stops after it's warmed up. Is this normal for this car? Or where is some probable oil/coolant leakage going on in this engine?
Thanks for any help.
