anyone use theses? good......bad?

 

Suck, use NGK in Nissans.

 

Denson Iridium long lifes are better then NGK any day! Thinner electrode with all around better technology and performance. Yes they are pricey but if you care about your engine and its performance and saving some fuel economy you will buy IRIDIUM SPARK PLUS period! NGK also make Iridium but when you do the research you will see that denso is better. Your talking Autolite 3 bucks each, bosch platinum +4 about 6 bucks a piece and NGK at 8.50 a piece and densos on ebay at 9 bucks each. DENSO is and NGK iridiums are FAR SUPERIOR THAN ANY OTHER PLUG OUT THERE.. By the way yesterday a friend had a Saturn with Bosch Platinums +4...........it was -40 yesterday here in Alaska and it would start. We took the plugs out to see if they were fowled and the third one we came to.....2 of the prongs were pusted off the spark plug and were on top of the cylinder. I hope BOSCH HELPS THIS SOLDIER OUT!

 

Use NGK's platinums or coppers.
Iridium plugs have mixed opinions about them. VQ engines like NGK's

 

So tell me what the guy says about Iridium spark plugs because as far as I know they are the best out there, hands down. Read the technology on them just like you do for AMSOIL compared to MOBIL 1! It is scientifically proven to be a better plug!

 

so....what does a CH-47 use? (j/k....I don't think gas turbines use spark plugs, do they?)

 

i have autolite double platinum in the 96. work fine, but use ngk coppers in the 98....and when i change the 96.

 

Please repeat after me: Japanese cars require Japanese plugs.

Please post the research on Denso vs. NGK. thx

 

What a load of crap....
So Yugos require Yugoslavian plugs? (That would be tough, since there is no Yugoslavia any more)....

Funny my Acura and Honda ran perfectly using Bosch plugs...

 

Stay safe and use NGK. Autolite might work, but even in the domestic world I've always heard Autolite were cheapos. I used them in an old Ford Tempo and they performed well, but that's a Ford Tempo. A professor at my college tried Autolites in an old '86 Nissan pickup one time and he said his truck ran like crap. He swapped them out for NGK coppers and suddenly everything ran nicely again.

I don't have too much comment about Bosch besides the fact that I have tried the Platinum+2 and +4's in previous cars (including that Tempo at one time), and I wasn't too impressed by the fact that the plug's TINY center insulator turned from a tiny stud coming out the center into a bunch of very thin protrusions pointing in the direction of the ground electrodes... and I did research about Bosch's regular platinum plugs, hoardes of USENET users were bashing the normal single-ground strap platinums as crap.

I believe the Platinum+2's and +4's did perform adequately enough when I had them in there. But these engines were lower-compression, and 4 cylinders. Not sure if I'd want to experiment like that in a V6 with the kind of efficiency and compression ours use, plus the fact that I like to use my car's power a lot more than I did those old 4-banger slushboxes

 

Not a load of crap. I totally agree. Yugos used Yugoslavian...lol...good comeback...

 

not really the point....

I use NGK on my 1970 triumph GT6 (which is British).....

these spark plug discussions remind me of the "which is the best gas" threads....everyone's got an opinion, but nobody has any facts to back them up other than "my car ran like crap with that plug" or "my car ran good with that plug"

 

and which brand of Yugoslavian plugs did Yugo's use, exactly?

 

Iridium spark plug specifications and benefits
Relatively recent advances in fabrication techniques have enabled the use of Iridium - an incredibly hard precious metal, for the construction of spark plug electrodes. Laser welding technology is used to weld the Iridium tip to spark plugs manufactured by both Denso and NGK. It's worth noting that spark plugs can't increase the potential power that an engine can generate but a more efficient spark will provide more efficient combustion and associated performance and economy benefits. A poor spark from a worn or low grade spark plug will reduce efficiency. An Iridium plug will produce a more efficient spark.

Notable properties of Iridium are its melting point - approximately 2450 degrees C, considerably higher than Platinum, and it's strength - approximately 8 times that of platinum. The table below compares the characteristics of Iridium with those of other precious/semi-precious metals commonly used in the construction of spark plugs.

There are currently two main manufacturers of Iridium spark plugs available in the UK. NGK have their Iridium IX brand and Denso have their Iridium Power spark plugs. Both are very high quality products using laser welding technology and manufacturing techniques perfected over a very long history of spark plug design and manufacture.

 

You make me laugh sometimes. BTW they have 4 igniter plugs at each clock position with 10 thermocouples that measure the heat. You can't argue the fact on the igniter plugs becuase there is only ONE type of plug. These plugs help produce 4500 plus horsepower but that is limited by the transmissions connected to them........blah blah blah. Oh and your fuel issue on a Chinook is TERRIBLE. 2600 pounds per hour. The CHINOOK carries 7000 thousand pounds of fuel and is capable of flying for 3+ hours and up to 12 with Extended Range Fuel Systems. Its total capacity.......oh you got me going IRISH44J.
