I’m in desperate need of a new set of spark plugs, as I'm currently running a used set of non-resistor ngk plugs with electric ignition. As my previous bosh plugs (ngk equivalent to bpr6es), 3 of which have become mysteriously bent and causing hard starting and misfiring under load.

The local car spares only sell Bosh spark plugs, which I now don’t like seeing as 3 have ‘bent’ having only done less than 1000 miles. And euro car parts website seems to be playing games, probably because of morons stockpiling blue workshop roll in place of bog roll.

So as I needed (well didn’t but as I’m not going to be able to go far in the coming weeks) a few other bits so I have something to do over the coming days/weeks, I thought I’d add a set of plugs (bit dearer than euros) to my eBay order from that well know mini specialist in stoke on Trent (who I’ve yet to contact).

 

Only, I’ve noticed that there’s no registered trademark logo on the boxes, and on all 4 plugs the stamped text isn’t consistent (either heavily embossed or really faint) and doesn’t match from plug to plug.

Well going by that. The brand name/plug type is properly centred. The 4 digit code is stamped on the hex nut, although as can be seen from the last photo the digits don’t line up with each other. The coating could be wrong although it’s hard to tell. And the sealing gasket checks out.

 

It’s just the inconsistency of the stamping both the code on the hex nut and the made in France/plug number that just doesn’t ‘look’ right to me.

I would strongly suggest you contact NGK to be sure. I could be wrong, but they don't 'smell' right to me.

You say that you are now running on a set on NKG, which I presume that you believe to be genuine.

 

Take them out, clean their exterior and lay them out just as you have in your 3 photos.

 

If the differences in position of print, stamped numbers etc: seen on the new set are similar to the old set, you are no further forward..........BUT.........if you can not tell one plug from another of the old set because printing, stamping etc: all line up in the same way, you will have good reason to doubt if the new ones are genuine.

Right, I have the plugs I’ve been running in the mini. It’s not running rich, just the last running it was idling/being moved around while on the choke. 2 with Japan stamped on them and 2 made in France. (I did say they were a used odd/but matching set)

But then searching around in the garage through odd boxes I have found a set of Bpr6es plugs and one new ish looking one in my odd and sods draw of my toolbox, witch I’m sure to be genuine as that was my crap draw from working in a garage. So if anyone needs random new calliper bolts (you can get away with only removing one and flipping the calliper up if just swapping pads) and other stuff, I have a draw full.

And a comparison of 2 of the new plugs on the left and 2 of my found old plugs witch I believe to be genuine. The other thing that now looks obvious to me is the thread on the new ones looks wrong.

Well that has blown my theory out of the water.

 

I agree with you about the thread. 

 

Try cleaning the old threads with some surplus lavatory paper, and holding two old plugs thread to thread and comparing it with an old and a new plug.

Will do, although while last out the other day I ‘panicked’ and bought a few extras along with white sprit. Seeing as I can’t go anywhere for a while with 2 potentially at risk people in the household, I might as well find something to keep me busy. And I have plenty of old tea towels, old t shirts and rags.

 

Although the stamping on the new plugs isn’t consistent, as it starts off heavy and the further round the plug the lighter and fainter it gets to almost nothing. And the threads, it’s hard to describe, they feel courser and are mre like just a spiral than a tread.

I do, but I want to ovoid going out if I have to, plus like with euro car parts, using my reg to find parts won’t work. As the mini originally had ballast ignition with points, were as it now has 12v electronic ignition with no points, so now needs resistor plugs. And the last time I was in the independent car spares place, all they seem to do is order the parts from euro car parts (which would be wrong) and stick there mark up on them.

 

I’ve cleaned up the threads and took some more comparison pics, but the more I look at the new plugs the more I notice that doesn’t look right. (who thought swapping spark plugs could be such a pita)

So what I’ll do, is as I’ve found an old set of the correct plugs, I’ll clean those up and run them and give it an Italian tune up the next time out. But how do I now proceed with the eBay seller? The last time a few years back I had an issue with something from this mini specialist I was basically told to do one ,and then that account blocked from buying from them.

I have a new set in boxes in my garage, I'll dig them out later and post a pic for comparison, they're 7's but I'm sure it'll give an idea.

I’ve fired off a message through the ngk site, I just have to await a reply.

 

Thanks PoolGuy, looking at those the stamping looks just as inconsistent as my new plugs. Could you take a pic of the boxes for me?
