Is anyone familiar wit the latest fake NGK plugs, I know they exist and have searched the web, but can't find any that resemble my issues.
The plugs lasted about 10 minutes in my 289ci Ford V8.
The writing doesn't look quite right.
The screw on tips have clearly been forced on incorrect threads, as they 'tear' off.
I have messaged NGK but cannot include photographs, so in the meantime what do the collective here think?

Look like shite to me. Where did you buy them? Cheap on the 'net I'd guess.

Online yes, local factors didn't stock them....
I dont know who you use, but Cafco motor factors, or even Halfrauds, or Europarts, would get the right ones in for you, but not necessarily from
stock
Something like this from fleabay or the like is possibly not the right place
These ok Pete? https://www.merlinmotorsport.co.uk/p/ngk-spark-plug-ap6fs-ngk-ap6fs
I'll have a look, i did have some nos pinto plugs knocking around, they were either bosch or ngk.
I haven't got anything pinto engined anymore, so if there are enough I can sort you out a set.
I have a feeling the plugs you have are genuine ngk, but ngk brazil, not japan. I'm not sure if the japanese made ones are available from ngk
anymore anyway.
The original japanese plugs have the plug number stamped into the body and have machined bodies, yours have forged bodies with no plug number, but do
have a batch code on the hex flank which is an ngk thing.
It's not just ngk, bosch and denso are also making their cheaper plugs in india, china, brazil etc, and the quality control has suffered.
I've fitted denso platinum plugs that have only lasted 1000miles ,and when removed the platinum tip has fallen off the electrode on 1 plug - the
supplier replaced them, but you expect platinum plugs to last 40-60k miles.

I’ve bought a fair few ods and sods from green spark plug and found them to be a legit firm. But it does make you wonder what crap is out there.

I have used Eurocarparts for rear wheel bearings under the brand name - Lucas - the first set failed in about 60 miles so they gave me another set
which lasted about 10 miles, didn't have another set but it seems even the known brands are not immune. The chepo set that I got from MDP for
less money have lasted thousands of miles!
Eurocarparts selling dodgy parts? Surely not. 
Own brand Chinese crap in Pagid branded boxes resulting in 2 police traffic car crashes? Surely not...
The Green Spark Plug company are a reputable, legitimate firm.
Did you go back to them? What did they say?
Just heard back from NGK, the plugs are genuine, and they're the correct grade for my engine...
He confirmed they supply the Green Plug Co.
No point going back for more of the same, just chalk it up to experience.
