NGK

[Wayno666]

My '95 V6 pushrod had a miss. Especially when cold. Pulled the plugs and checked wire resistance. Found this at approximately 2k miles on the plugs.
BTW what is proper resistance for the wires. Manual sas 5k at a foot of wire. Kinda made me laugh.
This plug could have been a real major problem.

From Amazon or eBay? There have been huge problems with counterfeit plugs, oil filters, and other parts from those sites. Lots of discussion on other forums about it.

5k ohms per foot sounds about right fir resistor plug wires.

No NGK plugs in my Ford's. Motorcraft or Autolite if I can't find Motorcraft.

Yeah.. I've always heard from people here that ford's pretty much want Motorcraft plugs for best results.

I ran some genuine NGK in my F-150 years ago because Summit Racing was selling “tune ups in a box” back then. Cap, rotor, plugs and wires, might have been a couple other things. NGK everything and it was cheap, like $50-60. Never had any problems but I was doing 50k tune-ups at the time. What’s in there now is either Motorcraft or Autolite (which is pretty much the same as Motorcraft).

Run motorcraft or autolites.

I run Motorcraft exclusively, Ford sold the Autolite name so I'm skeptical that they are not the same as Motorcraft. I know Motorcraft plugs last and are the correct heat range. I've never used NGK's but I suspect the plug may have been dropped at some point and the insulator got a hairline crack. The old guy(probably younger than I am now) who ran the shop when I started in 75 said that plugs were "good to the first drop". Old Maxwell House coffee ads said it was "good to the last drop" for those too young to have seen it.

NGK plugs are a good plug, if it's matched the vehicle correctly but some vehicles just prefer certain brands for some reason. Motorcraft and Autolite seem to the brands of choice for Fords. NGK and something else was a go to for Hondas. Hondas absolutely did not like much of anything made by Bosch. Maybe it's the same with Fords and NGK?

I ran NGK Iridium’s in my old Sport Trac, they held up well, no issues. Fords do not get along well with multiple electrode plugs like Bosch +2 and +4, or E3’s. Explanation is kinda long, Bob something or other who was here years ago had it down.

NGK is a GOOD brand and a reputable one at that. Like others have stated, some makes just like certain plugs. I run them and only them in my 87 Nissan D21 ( Z24 engine, 8 plugs ) I recently switched to NGK cables ( 10 mm ) in that truck also. 1000 times better, . . . for that truck.
You might want to switch to NGK cables as well, or switch to Motorcraft plugs and wires for your Ranger. I ran the Bosch Crossfire plugs in my 3.0 Ranger with no issues, but your results may vary.

NGK is an excellent brand, which is why I mentioned fakes on Amazon and the auction sites. NGK and Denso fakes are common online. So are other fake parts such as oil filters.

The Denso plugs in my Ranger now came from a regular auto-parts store, not from an online site, and the 4.0 SOHC engine runs great with them. I considered NGK, but the Densos were in stock locally.

When I was looking for plugs, I found that going to the NGK website was the cheapest and fastest way to get them, over Amazon , E-bay, and RockAuto, counterfits never even entered the thought process, but that is a good point.

I've always run Autolites in everything I owned that was American made and NGKs in Japanese made.

I have sold (and personally used) NGK since the early '80s at various foreign/domestic auto parts, & in motorcycle shops I've worked in, in both cars and in motorbikes. "Copper core since 1958". My Audi A4 B8 has 'em, my various BMW bikes use 'em. They're in my wife's Honda CR-V... I too buy them from reputable sources, as is mentioned above.
I have had exactly one fail on me. That was in a 1977 BMW R75/7 back in 1998 up in Crested Butte, CO. It just started to run on one cylinder (of two). Swapped plug leads side to side (wasted spark system), it didn't change. Swapped plugs side to side, there's yer problem. A quick sparkie replacement from beneath the seat and we were rolling. My girlfriend at the time didn't mind the flat twin vibrating a bit from her perch on the back of the seat.
