ngk better than bosch???

[A Quiet Boom]

To broad a question, better at what? performance, mileage or economy? Which model? Bosch Platnium vs. Standard NGK? etc.

My answer = Maybe

Hello

NGK is the best value buy. Bosch are high level and have some very special plugs but why buying Silverelectrode Bosch or Champion NG2īs for early 911 S when a standard NGK does perform good enough ?
However there are some applications where you have only Bosch or only NGK to cover.

May favorite spark plug companys are NGK, Champion followed by Bosch, Beru. However on some Alfas ypu still canīt substitude the Golden Lodges

Roland,

Are the Champion Gold-Palladium N-2G and N-3G spark plugs still available in Europe? They haven't been in the catalog for about ten years, here!

Hello

Nope, sold out since the 80īs but we have some NOS.

Golden Lodges!!!!!!

WOW they worked great on my BMW 2002Tii

I tried them in my 911 and they absolutely sucked, the engine would hardly run.

I wonder if Lodge had any sort of patent protection for the 4 electrode thing, or did Bosch or one of the other big entities buy out Lodge?

Not surprising, on some engines multiple electrodes can actually shield the spark causing poor performance. I have seen this type of plug by another manufacturer (Can't think of the name) in a magazine comparison test and they performed worse on "angle plug" type engines but about the same on engines with a straighter plug bore.

I miss that 2002Tii

one thing about the lodge plugs was it was near impossible to gap them..

Also I never could be bothered to index the plugs when I installed them, so with 4 electrodes chances are you would have the spark kernel in somewhat the correct spot... with one electrode apparently there is only one position...

Im thinking this is all very esoteric

Hello

Golden lodge multi electrodes looks like the father from modern multielectrodes but have slight different work principles.

The golden lodges father was the Bosch ringspark elektrodes used from race engines.

Most high performance engines from the 60īs to 70īs had problems finding suitable full range spark plugs.

The engine designer liked to have the spark fired up as far outside the plug as possible especially when the mixture became very lean.

One fine day selecting spark plugs to index them i found out that Bosch and Champion sparks always had the same position in the same 911 head. Now testing several heads it showed up that Porsche indexed the heads to match within 45° angle.

Years later I had Bosch spark plugs wich didnīt matched.
Looked at them and found out they wherenīt made in germany.
( MAL or US ? )
Asked a Porsche mechanic about that observation and he said that Porsche had so much problems runing there 911 2,0 S engines with then aviable sparks that they used every trick and they did it before on the Carrera & race engines anyway. That was a reason why some aftermarked spark plugs didnīt worked or let the engine run uneven.

He also thought that Porsche did it only with the heads wo have a helicoil thread insert. ( Well he only worked up to that time in the factory ).

I dont think it is to hard to make indexed threads on a good ( german made ) tool machine. The quest is who ever payed to that little things attention and could manage to have supplieres joining in.

Donīt think big companys like Ford or GM even where thinking about that as it would add to much costs.

Great thread, only thing I can add is that for 911's the Bosch of choice would be silver, not platinum. (At least for my SC). Platinums are a lot cheaper, NOT top of the line. Also on my BMW, ('84 533i), I used platinums at first, did not run at it's peak, switched to the correct Bosch silver tips, now it screams and barks.

NGKs are very popular w/ Porsche mechanics I've met, have not tried them yet in the 911 but would not hesitate to. Apparently the cars really like these plugs for some reason, (run great).
