The shop told me to use NGK 7333.



Is that what you use? If not, what do you use and why...I'm gonna get four on the way home tonight and replace them.

I use the Bosch WR7DTC called for in the Technical specifications booklet. No complaints and I replace them once each year even though they are not misfiring at all. good luck, Bob Blackwell.

I'm with Bob--I use the Bosch OEM plug. I just installed a new set yesterday, in fact. <img src="/forum/images/smilies/968/smile.gif" class="smilie" alt="" />

[right][post="4657"]<{POST_SNAPBACK}>[/post][/right][/quote]



was there a specific reason that he gave ?





my mechanic believes there is absolutely no difference in the top of the line plug from Bosch or NGK or Brisk in terms of longevity, performance and so on - all marketing hype according to him. his son races Porsches and he uses NGK, though.



I think my car runs smoother and is slightly more responsive with the NGK than the Bosch - I change the plugs once a year ( around 20k mi ) even though they function perfectly. It's cheap, so why not ?

I once put fancy (expensive) plugs in my 928 and the (really good race) mechanic I took it to for some tuning work took them out saying that it ran better with stock plugs. Not sure if it's so but that's what I'm running now...stock.

i tried a new set of the stock bosch plugs and then a new set of the ngk iridium - noticeable difference and improvement in the ngk - tossed the bosch - probably not much difference between the ngk and any other high end plug, but the difference and improvement between standard plugs and high end plugs are documented from almost every manufacturer

I put in NGK 7333 plugs, runs great! They're the ones my shop recommended to put in.

I purchased my NKG plugs from Sparkplugs.com great service and fast shipping!

Do you feel they are much better than Bosch Platinum 4 Spark Plugs?

Like Greimann, I'm running on NGK 6637. About 23k smooth trouble-free miles so far, at about 22.5 mpg.

this is a lot like alkaline batteries



you probably won't see much of a difference between any premium plug (platinum, iridium, etc) in the performance area - where you could possibly see any difference would be in longevity - this will depend largely on your particular driving though



you will however, see a significant improvement over a standard plug (original bosch, etc), as is documented by almost every plug manufacturer



whever you see charts, it's always standard versus premium - i haven't yet seen any charts of one premium versus another

I've heard that the only reason they developed platinum plugs were for their durability; extremely long lasting but not the best conductor. The iridiums on the other hand are much better conductors which is why they are used primarily in race applications.

Flash said "this is a lot like alkaline batteries"........UH...no.

Kinda off topic but worth mentioning anyway, pet peeve ...insert here >

The "bunny" brand batteries actually use less of the charged medium than the "coppertop" brand. I am REALLY into halloween and the usage of props with batteries. On one of the "other" forums a fellow halloweener acutally test killed about 10 each from random packs bought at the store with the same date of manufacture. The "bunny" always died sooner. In fact some of the "bunny" rechargable "stacked batteries" had less voltage than their counterpart made by the "coppertops". Stackable batteries are voltage rated by the # of button cells they contain, more cells, more voltage.

OK really off topic. Sorry. I don't know ship about spark plugs but it sounds like NGK is going to be my next set.



Sorry about the off topic ......ramble, (mumbles to himself, as he hobbles into the shadows again)

after 9 years on the road using a lot of different wireless mics, and other devices that need batteries (we would go through about 100 a week), i can tell you for sure that the issue with the alkaline batteries is the duration of that voltage - in low current draw items, the energizer lasts longer, but at a lower voltage - in high current draw items, the duracell maintains its peak the longest, but then falls off fast - on the shelf, the energizer lasts longer



that's what i meant by drawing the analogy - it depends a lot on how you drive whether or not one high performance plug lasts longer than another

Flash,

OK got it. DC motors draw lots of power compared to a wireless mic.

Thread abuse has ended. sorry WOB

not so sure about that one - that's why we used the procell (industrial version of the duracell) - we could get about 2 hours out of a procell, but only about an hour out of an energizer - at the 1 hr point, the duracell was down to 8.9v and the energizer was down to 8.6 - at that voltage the signal was sketchy on the energizer - in further testing on other devices, the duracell would fall very fast from there, but the energizer hovered at 8.5v for almost twice as long - the wireless wouldn't tolerate the low voltage, but the other devices would



sprinter versus long distance runner - ironic that they chose a bunny to be the long distance runner



i'll put energizers in my flashlights and duracells in my wireless and any device with a specific operational voltage requirement



there's my "plug" for each
