I work for the local mazda dealership and my boss just found a huge box (well over 40) of spark plugs. the NGK N3Z4-18-110 RE7C-L ones.
I've got a few questions.

1) Are they safe to run in a 12a?
2) They say leading plugs, does it really matter? i've got enough for over 10 tune ups now, can i just use the same in both?
3)If i cant use them, or only for leading anyone interested in picking some up?

THanks a lot guys!

 

Hot damn man! Im unaware of differing plugs for leading and trailing but I would take some off your hands

 

Those are rx8 plugs. I run them in my stock 12A now. Works fine. Supposed to last a lot longer.

 

i run em too, they are a much better design than the previous plugs. if its a leading plug, run it in the leading, they are probably too hot to run in the trailing spot

 

If you want to get some of them gone here locally, I'd be interested in a pair or two

 

I guess your boss doesn't expect anymore RX8 tuneups in the future

 

Haha alright guys, I've gotta wait a bit for them to "dissapear" from the shop if you catch my drift. Anyone local to MN I'd be willing to sell them. My boss, I work in the detail dept btw, knows they're worth something. Once I figure how much he wants for them ill let you know what I want for each plug if anyones interested still! Thanks for the replies too!

 

retail is like $20/ea. Im running them in my S4 swap

 

Hope you keep your job long enough to get em

 

Haha im not worried about keeping my job..
I've got stories for days about other idiots that i no longer work with hahahah
