Platinum NGK Spark Plugs

That came from a bunch of GM techs... and it's obviously a load of crap

You are not kidding it's a load of crap.

No wonder GM is leaking billions with morons like that designing their stuff.
When the do the next round of downsizing those idiots deserve to be the next to go.
Maybe they should take a trip to Europe and find out how to do the job the way it should be done.

By the way another NGK user here as well.
Used to use Champions but had a few fail and switched to NGK as a result and never went back.

Cheers , Pete.

I've used NGK's for most of my mechanical life.

I do have to point out, in defense of the platinum +4 series plugs, that while they do "shroud" the spark a bit, they're also designed for use in higher compression engines, which may quench the spark due to the resistance created in the atmosphere of the combustion chamber.

For OEM cars, they solve a problem that doesn't exist to begin with, when dealing with "new" conventional spark plug technology. In that sense, their feasibility is destroyed, making them essentially a gimmick, of sorts.

In defense of Bosch in general, they do make several other products that I choose over others... just not spark plugs.

I am a fan of Bosch, as an Audi driver, as well I have installed a lot of Bosch components on my other cars, but those +4 plugs really do seem like a gimmick.

I put the Platinum +2's in my 97 escort (4-door, not ZX2). I noticed right away more power on take-off, and jumped from 33 to 36 mpg.

Could partially be due to plugs not having been changed recently at all, but I have no idea. A buddy of mine tried them in both of his mustangs, V6 and V8, and both cars fouled them pretty quick.

I would surely attribute that to them just being fresh plugs.

I doubt the "techs" referred to are in R&D.

I put platinums in the F150. No discernable performance/fe differences whatsoever.

I put "pulse plugs" in one of the Tempos. They work well enough too. Not saying they are any better, but they work.

Whoa! - no... I hadn't noticed this before, but I'll clarify now - The "Techs" I was referring to are "Automotive Repair Technicians". They're the GM licensed repair guys that work at the dealership.

The worst part about that experience was hearing that same line of crap from more than one dealer's "technicians". It was as if they'd been fed some line of garbage about how installing bosch platinum plugs might void the warranty or something... (I'm sure there was a TSB on it, at some point.. it just sounds like something GM would say.)

There are two different kinds of Platinum plugs available from Bosch. The really expensive ones that were made for the early 911s (which before that fouled out or eroded plugs at a horrifying rate!), and the cheapie ones that you can get everywhere.

The latter are pure crap, IMHO. The QC is spotty at best; I know more than a couple of people who have had the speck of platinum fall right out of the plug into the combustion chamber! They also foul quickly on older cars that tend to run rich. Their +4 and +2 plugs are the same crappy plugs with extra outer electrodes.

Bosch's other plugs (copper, silver, et al) are pretty good, but the cheap Platinums should be avoided.

personally for a maxima i would go dual platinum plug because the max is a performance aluminum block so a better longer lasting plug will save you in the long run in spending less and i have noticed a slight increase in power and mpg i do not have a scangauge to read yet but i could tell

I run cheapo platinums.. installed in 2005. Now on its second sube approx 65k miles, on a carbed 1987... which just read 22 inches of mercury rock solid (ironically, less than an hour ago)

if the plugs are failing, target everything. plugs are just the end...
I give them 2 thumbs up
rich conditions, way way freaksihly below zero (-18f and beyond) to days like today, with a gulf slick burning haze and a 80F temp reading not matching the repulsive slop it feels like.


what happened to this thread, its like a chunk disappeared.
