NGK Changes Name to Niterra North America.

seems a little odd, you'd think they would want to keep the brand recognition they have built over decades.

A guy on an auto board was shocked when a set of spark plugs came in a Niterra NGK IX box. He thought they were counterfeit, but nope, they were NGKs.
 
I remember NGK plugs were the go-to on 2 stroke PWC engines. Nothing else ran right, and some of them were really cranky about their plugs. Kawasakis in particular ran like poop on anything else. Other things would run but they tended to foul the plugs.

I always ran NGK in my 2-stroke dirt bikes. Bosch and Beru plugs would often foul at the worst times (like halfway up a 45-degree hill climb).

The news releases about this say effective from April 2023 but first I've seen of it. My cars use Bosch but can use an NGK in one of them.

Supposedly my wifes M4 would run on NGKs but it blew the porcelain apart on one of them as soon as it was under a load. I pulled all the rest of the plugs, checked the gaps and replaced the broken plug and took it for a test drive. The same thing happened on a different cylinder so I said screw it and bought OEM M branded Bosch plugs from the dealer and didn't have any further problems. Lesson learned.

I've never heard of this with either NGK or Bosch. Was her car a stock M4? Or was it tuned?

This sounds like a pre-ignition, detonation issue.
 
I've generally learned to stick with OE plugs in most things. Just had too many odd problems with running other stuff. The Mark VII came to me with relatively recent platinum plugs (Autolite? I don't remember) and it had a rough idle and detonation issues. Swapped them for the stock Motorcraft copper plugs and all of that went away.


my leaf vac even has a B&S OE spark plug. Not because I care that much about it, but I needed to do an oil change and an air filter, and buying the tune-up kit with the filter, oil, and plug cost slightly less than buying just the oil and filter.

It's all stock except for K&N filters and aluminum charge pipes that replaced the factory plastic pieces.There are no issues whatsoever with the OEM plugs, but it may have detonated with the NGKs in it. It only gets fed top tier 93 octane premium so it shouldn't have detonated unless the recommended NGK plug was the wrong heat range which is entirely possible.
My Audi is tuned and makes right at 150hp over stock and runs perfectly on the stock NGK plugs FWIW.

Could be. I was done dicking around pulling and replacing the plugs just to get the same results because there's a fair amount of disassembly involved just to get to them. The car's coming due for the 60k mile service so It'll just get the right plugs the first time.

:thumbsup:

Modern cars are sensitive to the plug's heat range.
