NGK Plugs- whats the deal here??

[steveb24]

why, when i put the plug in, they have a copper top, but when i take them out, the copper top is missing. I noticed this yesterday. 7 of the plugs, that i put in exactly a year ago, were missing the copper top. The one plug that blew and i replaced it 3 months ago, still had the copper top on it. Where in the heck is the top going??? I looked in the COP and didnt see a thing.. i must be blind or stupid, but i thought it was weird. Is there any reason for this?


PIC: How it looks when new (copper top on):

PIC- the one W/O the top is what 7 of them looked like:

I cant even see what you trying to say the pictures look the same. Maybe you should use paint to edit it and put a red line near the part thats missing.

look at the 2nd pic. The bottom plug DOES NOT have the copper tip anymore. Hope this helps, but i dont know why they didnt, or where the tip went

I cant tell what you meen either from those pics, too blurry

 

[steveb24]

ok this should make it nice and clear..

doesn't matter, as long as the hour-glass(for lack of a better term) tip is on and there are NO threads showing, it's fine.

So are they copper coated Randy? What happens when the copper wears off? I like the NGK plugs. What's your opinion?

Randy is the man! :SNSign:

hmm.. so i wonder than, where IS that tip going? since 7 were missing, and i didnt see any of them.



thats good to know tho that it dont matter, but still kinda weird. thanks randy for takin the time (and for that order last week)

NGK are the only non-Motorcraft plugs I would ever consider using.

when they say copper plugs its not the connector thats copper... its teh electrode and conductor inside the plug... i think the connector is tin or something lol

ohh.. well that clears up the fact that nothing is being harmed by that, i still just think its wierd that the connector dissapeared. haha.. anyways, it runs great so who cares.. btw, i really like the .38 gap, it feels strong
