'Fake' AC Delco 41-101 spark plugs ?!

[SmilingSam]

OR are they ?

just got much cheaper ($4 ea vs $9+) 41-101 from ebay and have looked at them from a 'engineering' point of view NOT just a cosmetic POV.
(multiple utube vids just seem to use cosmetic comparison not any 'real' info concerning how they are fake (no real evidence that they are fake just A$$pinion, imo) - ie ink color, diff cap color, diff tip shape, diff boxes, etc).

also, since when is price a pure indication of quality ?

Stamped on these plugs, is assembled in usa with domestic and foreign parts.

Also is the big NGK stamped on the metal, which indicates the foreign parts bit.

the tips look identical to those in mh now (983?), but are diff from some pics of iridium plugs on ebay and elsewhere, while the same shape as some as well, the 'iridium' ultra small part is not there but a more tapered point and honestly more solid and lasting? shape too.

Some miss the point of a spark plug, it is ONLY there to produce a spark-from tip to ground, it is NOT a fashion show, so it ONLY needs 2 solid aspects of good engineering, a Tip that will not break or wear/burn off & conduct the HV efficiently and a very good ground via the threads, that is it !!

of course the wire connection needs to not rust etc.

the coating on the threads need only be good at conduction, so color of metal coating not important and besides bare metal would be good as well so a deposited metal surface is a plus.

i personally did not thinks spending $150 for wires as necessary, so bought wires with actual wire but also suppression material to prevent large/any RFI, a good thing for radio and ecm and tcm and all things electronic !!

So please if anyone who has engineering/material knowledge let me know where my thinking is incorrect !

Thanks !!

What engine do you have ?

comments of 41-101 fake plugs is concerning (does it matter at all on this topic?) my 2007 w24 chassis.

I ordered mine from ebay, they looked like the originals.

UPDATE- with closer look and with reading glasses, my 'fake' acdelco 41-101 have stamped on plug - made in USA with NGK parts, so if fake then a nice good NGK fake which i consider as good as any plug or components.


As to whether an iridium tip, who knows and does anyone know if any plug tip on ANY specific plug is iridium or platinum or any 'special' durable metal ??


how ?
